Headers. Bolt on, hold on and try to not grin like an idiot.
 
Hey guys/gals.

M62 owners, both 4.4 and 4.6 (possibly 4.8is's too) versions, I have a treat for you.

Just so happens that a friend of mine is building custom headers. He built a set for his s62 and compared his dyno numbers against his dyno with Dinan headers and he gained about 25hp with 23 ft lbs increase, OVER THE DINAN's. That's like 65hp over stock!

This is great I thought but when I asked him about the "lesser" V8's he shocked me and said that since the ports and bolt patterns were the same that his headers would not only fit on the 4.4 and 4.6, he tuned his secondaries to mount on his e53.

So I asked if he'd be making a few more and his answer was "yes"

I give you the "Unicorn" header.

FROM THE DESIGNER/BUILDER




*"I started development on these headers April of 2014, right after I had finished the M5 wagon build. What I thought was going to be just a few months of work, turned into almost a year long challenge, but absolutely rewarding in every aspect. By every definition I had underestimated the cost, effort, time, blood, sweat and tears required for such an endeavor. Going through this exercise though, gave me tremendous insight into what really goes into developing such a product.*


So right about now, you’re asking yourself why? Why go through all this trouble and expense? The E39 is an aging model, everyone else has moved on. Well, I don’t really care about everyone else. If you’re reading this, and you’re like me, we are not ready to move on and let go. In fact, we find every excuse to dump more money into the beast. I plan to keep my E39 M5 for as long as I can. We will all be probably driving electric vehicles in 10 years, but the legacy of the gasoline engined e39s will forever be a permanent part of my life.***


About a year into the M5 wagon build thread, when I was refreshing the S62 that was to go into the wagon, I had a chance to study the Dinan headers that was also going into the wagon, since they were off the car collecting dust on my garage floor. As I observed the Dinan headers, I marveled at its complexity and quality. But as days and weeks passed, (during those staring sessions in the garage after dinner and before bed times - you know exactly what I’m talking about!) staring at them closely, I started seeing things, and asking questions.*


Why did they do it this way? Why didn’t they do it that way? Why is this thing like this? Why is this not like that? This was especially the case when I installed them for the very first time on my Anthracite M5, in my garage floor, on my back! Right about the same time, I had a set of Supersprint headers lying around from a parts car I purchased – same car where the S62 I used for the wagon came from. I also studied the Supersprint design and started asking a bunch of questions. Why 4 into 1? Why spring clamps? Why modular construction instead of solid 1 piece design like the Dinans? Why this? Why that? Why does the SS merge collector hang so low down on the car? Etc, etc.*


Also, at about the same time, I went with a group on a Saturday morning run up GMR where I had a chance to hold in my hands a set of Evolve headers that a fellow enthusiast just purchased. Staring at the Evolve headers, first question popped on my mind was why aren’t these equal length? Where’s the stepping? Are these really made in the UK? Lots of questions indeed.**


I don't consider myself an expert on the subject, far from it, but I’m not completely foreign with headers and header design. Prior to this project, I had been playing with 4 different sets of headers on my E60 M5 (RD Sport, Agency Power, RPI and experimenting with my own variations). Previous to this, was playing with euro headers for my old E28 M5. Add in all the wrenching I’ve done in the garage for 20 years on BMWs; theory though, was learned as I went, consulting with experts in the field and master fabricators. The rest, I just mix in the passion and love for the hobby.**


After observing closely those 3 brands of headers mentioned above, I said to myself, “man, I wish there was a set of headers that had all the features I liked.” Also asked the question, “can there be any more improvements made over what is out there?” “Can it be done better?” I do believe in the equal length and tri-Y design of the Dinans, but I love the modularity of the Supersprints, I hate the 2-bolt flange type on the Dinans, I certainly didn’t like the quality of the Supersprints and the Evolves. I didn’t like that the Dinans were ceramic coated. I didn't like that the exit pipe was only 2.5" diameter. I didn’t like that certain primary runners were angled so aggressively at the entry flange that the only way to screw in the nut was to move the entire header 1mm at a time closer to the head, tighten the nuts 1mm, rinse and repeat. I really loathed the fact that the front subframe had to come down to install any type of headers. But the one big question that kept coming back to me was, could there still be unfound horsepower to be gained by improving the design?*


What if I were to combine all those features that I liked in the different headers and took out the features I didn’t like? I needed a stronger and more worthwhile reason to justify this whole exercise. Like…more power throughout the rev range? Is that a good enough of a reason? But how much more power can be had? And at what cost? Wouldn’t it be just ridiculously amazing if we get to that point? Such deep probing questions indeed.


Finally got the dyno results on my own header design. For those that are looking for more power, this can be a good option. My headers had a gain of 25hp & 23 ft/lb over the Dinan headers. So over stock, perhaps 65 hp, can be more with some tweaks and a tune. Test car used was my 2000 540iT that underwent a full M5 conversion build a few years ago."


Without disclosing too much, I’ll share with you what we did. I’m sure you’ll understand if I leave out some details for obvious reasons.*


Working with a master fabricator, we gathered every spec I could find on the S62. Taking into consideration for the design, *the following:***


Engine configuration

Maximum RPM range*

Useable RPM Peak HP/Peak Torque Discplacement/Bore/Stroke Compression ratio*

Throttle body diameter Intake/Exhaust port dimensions*

Intake/Exhaust lift at valve Intake/Exhaust duration at .050 lift*

Intake/Exhaust opening at BBDC Intake/Exhaust rocker arm ratio Intake/Exhaust lobe centerline Intake/Exhaust closure at ABDC***


The specs above in addition to a few other considerations helped us determine all aspects that were built into the design. With my own wish list of features, we made the every effort possible to not leave anything out. In other words, if I was going to set out to build my own headers for the S62, here is my chance to incorporate everything I can and leave out things I don’t want.*


The springs hold the merge collectors against the runner that feeds it. A double slip joint is used at each merge collector, all other joints are butt joints and TIG welded. The whole system, once in place is pretty rigid and won't run the risk of "coming apart" from vibration.*


The double slips allow the header system to expand as it heats up and at the same time alleviate any stress or pressure at the joints, hence cracking or stress fractures are completely avoided. The springs allow the system to expand and still keep things in place. At maximum expansion, the spring tension is nowhere near its tensile limit, since the spring hooks are positioned exactly to minimize spring tension.


Another point I should mention was the issue of dropping the subframe to install headers. I wanted to see if I it was possible to install headers with the subframe in place, along with the steering box, steering column and hoses in place. The packaging constraints of the headers were many. If you are familiar with the lower part of the engine bay, there isn’t much room down there.*

Until the nuts are finally torqued down, the whole system has some flex to it to help in the assembly. The install is very straightforward.*


For someone who doesn't have access to a lift, it can still be installed on your own.

Also, knowing that the exhaust ports on the S62 heads share the same pattern and size on the M60/M62 engines, I thought it would be great if these headers worked for the 540i/740i brothers looking for headers for those powerplants.**


So, fast forward to today. My headers were designed and built for every reason you can think of and for no reason at all haha. Are these what unicorn dreams are made of? Who the hell knows. But I know that I’ve been dreaming of these headers for quite a while, and to see them finally a reality is absolutely astonishing."


So, here's what you get;


4 -2 -1 (Tri-Y) modular design*

True equal length runners*

Full T304 Stainless Steel construction 100% Mandrel bent tubing*

TIG welding, fully back purged w/ Argon Solar Flux type B in cases where back purging is not applicable*

Laser cut exhaust port flanges*

Oversized exhaust ports to accommodate ported cylinder heads*

3” V-band flange exit pipe*

Profiled merge collectors*

Double-slip joints w/ stainless steel spring clamps*

Tuned stepping*

Removal of front subframe not required for installation*

100% of raw materials & supplies sourced from USA manufacturers.*

Mandrel bending, welding and fabrication services provided by USA vendors.

Any questions?

Those gains over Dinan don't surprise me. I don't think they even do headers anymore.

Those are pretty though. Very pretty. If I had a m62b44 or m62b46 I'd be jonesing.

I guess being first... I'll ask the question... what's it going to cost? ;)

Not cheap I'm afraid but considering the effort, man-hours and materials not to mention the possible gains and more gains with a good tune... (pause for dramatic effectl)
$5,500 for the headers and if you want to add the secondary pipes with cat-delete and bungs for O2 sensors it's another $600.

Fits S62/M62/M60 V8s

crystalworks 06-18-2016 10:27 AM

Pause for dramatic effect is right lol. That's as much as some people pay for their X5's.

Don't think he'll sell many at that price, but then again, it probably wasn't ever his goal to do so. Still, many props on seeing an endeavor like that through... custom headers are not fun in the cramped engine bay of a V8 BMW.

Hey is this M5Jed from the M5board that built those headers? They look familiar from the ones that the M5 board member (M5Jed)fabricated. Considering the Dinans were 8k when they were offered this is a relative deal but costly for the average X5 owner.

True, but when they were offered, the M5 was a $75000 vehicle. There is a reason Dinan stopped making them... I bet they didn't sell many even during the e39's hay day.

But, again, not to take away from this guy's work. It's incredible, and if he can find a few people willing to pay that... great. I'm willing to bet this was a thing he wanted for himself, and if others ask... he came up with a price that would make it worth his while for the trouble. Although he did make a jig, so maybe he did intend to sell. Who knows. At any rate, it's a cool set of parts and he got his desired result. My hat's certainly off to him. :thumbup:

Plattus1000 06-18-2016 06:33 PM

Jed is indeed the architect and brains behind these. Yes, they are expensive.

Find me a guy with a 4.6is who wouldn't love to drop these in and Sa-moke a 4.8is next time they had a chance.

I'm planning on some forced air down the line so opening up the flow on the back end is a real treat.

As far as cramped space, if you took a lunch break to read that whole thing, it's all modular, shouldn't be difficult at all for the e53. One custom weld if you're keeping cats and a steep downward bend for the secondary collector.

For the price... I think FI is attainable and the gains much greater. And I'm curious if the 5spd vs. the 6spd trans would still have the 4.8is be neck and neck? An S62 with ITB's and other improvements over an M62 is going to benefit more from these and the HP gains are going to be much more modest on the non-M engine.

Again, not saying these aren't worth $5500 or taking anything away from the work done. Being able to install these without dropping the subframe is a huge plus as well. I'd just be very surprised if someone with a 4.4 or 4.6 would want to do these vs. a Vortech.

Plattus1000 06-20-2016 02:42 AM

Good points to bring up. These aren't cheap but either has the $18k we put into the wife's X5 in the last 2 years just to keep it going. It's all perspective I guess. I've seen $5k stereos and $5k in wheels, either make the car more fun to drive unlike this.

As this car is my mid-life crisis car and lifelong project, I might as well go for the good stuff now while I'm earning money.


I am running a 4.6 in my wagon and plan on installing these with before and after dynos. All questions should be answered there.

I will say this about the headers being worth what they cost:

If I went VF supercharger, for $5-6k I get a kit and for another few grand in testing/tuning/parts I finally get it up and running, I'd worry about things breaking. With headers, these headers, after the install and tune, I'm not only not worried about things breaking, I am not wondering of I could have passed up on better headers.
People who've gone evolve or SuperSprint sometines question if they should have gone with another setup. I won't be doing that.

Now if the gains are above 40hp, I'm totally happy and if I can hit that mark in torque, also thrilled.

It will make the power loss from running a supercharger (50hp to run the damn thing) seem not so noticed. But, even if I decide to keep things naturally aspirated, what fun it'll be.

Truth be told, if you just want power for the buck, an LS is the only answer but there's a fun challenge in getting more power from a stock engine that retains all the features of the stock vehicle. (I know mjne isn't stock but it is a bmw engine and almost exactly like the 4.4 I had originally)

I don't love bmw's for their economical prowess. Smiles per gallon is all I'm in it for.

Wait till they get installed and I get some real numbers off the dyno and then we'll know. I have high hopes.

-side note-
My goal in the entire engine swap on my wagon was to beat M5's. As is, I am neck and neck in the only 3 races (safe areas to do so) I've been in. But the look on the face of the M5 owner as I pull away is what I'm really in this for. If I can do that naturally aspirated, I'm happy as can be and might not even get a blower down the line. Who am I kidding, of course I'll force air but just for funzeez.

crystalworks 06-20-2016 09:04 AM

I totally admire your dedication to going "all out" on the 4.6 with parts as nice as this. My sensibility bone would just keep getting in the way from even considering a $5500 set of long tubes. I'd be surprised at 40hp at the crank. My 4.6L Mustang didn't make that many after BBK long tubes and a tune. Came close, but those long tubes cost $500.

True, LS is the "cheapest" way to big HP. I, like you, prefer a BMW engine in a BMW... but the LS would be cool too. I'm definitely hooked on your project and if you've got the scratch to go with these, AWESOME! Looking forward to seeing what the results are for sure.

TiAgX5 06-20-2016 09:54 AM

Correct me if I'm wrong.

When choosing headers for FI, the headers should have the shortest tube length possible, and Tri-Y is not needed.

The Dinan headers were designed to be the "icing" on the supercharger "cake". A major advantage of minimum length primary tubes is less heat soak underhood (running FI increases underhood temps, the added surface area of equal length primaries adds even MORE heat underhood).

Equal length Tri-Ys are best suited to non-FI engines.

Those who have tried to "chase" a few extra HP by optimizing exhaust pulse/merge/flow with FI, have found little gain after significant effort/cost. A simple pulley change will give you all the HP you could ever want, enough to grenade the motor.

Very true!

Or changing gear ratio.

J.Belknap 06-20-2016 11:49 AM

Pretty neat!

Plattus1000 06-20-2016 02:39 PM

TiAgX5--- I honestly don't know. I will say that I trust Jed and from what I've read, have heard nothing to indicate that anyone has convinced him to change a thing. If you're correct, I'm guessing the difference on a real-world daily driver would be hard for me to notice at the wheel and at that level of perfection, I should have replaced the crank and pistons with lightweight versions and done a full extrusion hone on the heads to maximize flows, I did not. I'm just looking for the best I can get without building the space shuttle.

J. Belknap--- Thanks. How's your X doing? Love reading the story of how you landed that rig and got it home.

Crystalworks--- who knows. Dyno, dyno, dyno. I'll know then. I have found a slight difference in a domestic hp number compared to a German hp number in comparable displacement engines. If you've seen the inside of a 4.6is exhaust manifold, you'll know that just about anything should be better.
If anyone thinks that bmw didn't half-ass the exhaust manifold on the 4.6is, check this garbage out. Anything would be better.

J.Belknap 06-21-2016 09:37 AM

The X5 is doing great, Plattus, thanks. I just do regular maintenance, tiny improvements on the Dinan stuff and drive it a ton!

My exhaust is stock other than Tubi catback, but if the cats go I will replace them with some 200 cell HJS units. Very quiet at idle and smooth roar at WOT.

I imagine the sound from those headers is loud. :)

Plattus1000 06-21-2016 12:53 PM

We'll see soon enough. Love your rig by the way. Yours an BCredliner's are benchmarks. A few others too but from my first days reading in here, you two stuck out. My wife still won't let me mess with her exhaust. It's kill'n me.

For turbo, absolutely. Getting the turbine as close to the heads as possible is best to keep the gasses hot and moving. Heat is power. But for a blower...I think all you are trying to do is keep the air charge temp down so you don't lean out and detonate. But the real answer for that is probably a good intercooler, more fuel and a cheap heat extractor, not coating the pipe.

It looks nice and is probably a high-margin component for Dinan, though.

Plattus1000 07-04-2016 05:08 AM

I'll let you know what I get on the dyno as soon as they arrive.

Love the workmanship and attention to details that are NOT normally found anywhere in the aftermarket. Nice work!

Speedfreak81 07-20-2016 04:45 PM

Dear GOD I'd love a set of these on my 4.6.

Plattus1000 10-17-2016 08:23 PM

Just a tease but these show up on Thanksgiving. I'll do my best to install an X-pipe, delete the cats and possibly add a muffler at some point before the New year.

I'll do a dyno before and after and I'm expecting decent gains. If all goes well, Jed hinted at a group buy like he did on m5board.com

I think us 4.6 guys with e53's will have to use a custom secondary as the slope down is much more aggressive than on the sedans. That being said, these should fit the 4.8 and 4.4 as well so it could be a nice addition for those wanting a little more pep.

crystalworks 10-18-2016 12:39 AM

I'm certainly in for the sexiness... though they are incredibly out of my price range at the moment. :) :( Hope you get good gains from them.

Being honest, they're out of my price range too but I couldn't let them pass. Even without gains, they're so beautiful. If I could afford 2 sets, one set would hang on the wall.

I'm on a trip in California currently and figured that while here, I'd meet up with M5Jed for the first time while here:

My wife and I met with M5Jed and his better half (the owner of an e60 m5 btw's) tonight and broke bread with them at Buca di Bepo in Anaheim.

What cool people, both of whom have a real passion for bmw's. GPS got us close but it wasn't till I saw the "neighborhood car lot", about 7 bimmers all hudled together on the corner of their block along with the full 3 car driveway complete with a front clip removed m5 begging to be put back together, that I knew I was in the right place.

Jed Welcomed us and took us to dinner down the road. Great conversation and food. These guys are great together and hearing Jed talk about his work, its clear that we've not seen the tip of his mental iceberg. This guy, so much untapped potential still left in him. I'm not willing to let any cats out of any bags but I'm anxious to see what he shows us over the next few months and years.

With luck, he'll be up in my hood (Seattle) in 3 weeks where I can return their hospitality and continue to learn more about them. Quick trivia; one of them drives like a "grandma" Hint: he did an s62 swap into his wagon... lol for some its the challenge and pride and for some, the glory and bragging rights. I got no sense of ego or arrogance from him just a desire to try and do things better because he can. If you ever get a chance to say hi at bimmerfest, you'll know what I mean. Once again, I'm honored to meet yet another bimmer bro and share a passion. Thanks Jed.

Plattus1000 12-06-2016 09:54 PM

Last month I visited with M5Jed in California. Then he and his wife came up to Seattle bringing with him an early x-mas present.

I'd planned on putting these on right away but time/$ are going to keep them on the shelve until after New Years. This gives me the opportunity to piss off the wife by having them in the living room which I love.

Keep in mind, I'm putting these on a 4.6is engine but the engine is in my wagon so there's going to be a slightly less aggressive turn on the secondaries. I'll have to fabricate an extension to fill the gap from the missing cats up front.

Still, the dyno, I know. It'll happen. I'm as anxious as you are to see the numbers.

:wow::drool:
Don't waste your time and money to fit them, better you just ship them right to me :D

They are just a piece of art, therefore placing them into your living room is just fine :rofl:

I have Supersprint headers in my M5, love them. M5board had a group buy a couple years ago, it was a bit of a mess but in the end it was well worth it.

Plattus1000 12-07-2016 01:20 PM

It would take Jed 6 months to make that many! Wow.
Well, on your m5, I'll assume you felt a difference and definitely heard one. Ever get it on a dyno or one of the other guys on m5board probably did. Was +25-27 hp about average? What about torque?

Plattus1000 01-08-2017 01:52 AM

I will to the best of my ability, try to have a before and after dyno posted before mif February. Done @ DUDMD's shop so he can tune the engine. That and, it's Dima.

I'll still get another dyno before all that on this tune so that question gets answered.

Jed made these for the s62 but they'll fit the holes for all these blocks so we'll get an idea what gains can be had on a non s62.

If by chance you've got a spare m5 steering box, m5 sway bar or anything else I should mod while in there, I'd be forever grateful. These last few months wiped me out. I think we'll drop the engine so it'll all come out. Good time to look for leaks and whatnot on this girl's heart. Perhaps a good time to attach those engine badges I had made up.

In any case, I think it will be great to see what Dima can pull out of these on my 4.6 because on the 4.9 s62 Jed got impressive numbers. 26hp over Dinan M5 headers doing the math, thats over 65hp over stock.

I might need a muffler. Any way I can cut and weld 2 small ones together at an angle to replace the resonator? Butterfly cutout... Yes. I hope, it all costs $ I guess.
On the headers:

If you were on the fence about purchasing a set, I know they're expensive and you'll probably wait till dyno numbers come in but this might just might be the thing to push you over the line.

Just look at what you get as extras!!!

http://i326.photobucket.com/albums/k...ps8c9t5gyd.jpg

http://i326.photobucket.com/albums/k...psiqflvkpo.jpg

There are decals too but I'll post pics of them on the car once applied.

On to that dyno. Yo Dima! I'm bring'n the heat.

Speedfreak81 01-08-2017 10:26 AM

Can't wait to see before and after numbers on a 4.6!

bcredliner 01-08-2017 11:56 AM

Very pretty!

For clarification- The dyno runs were with open headers
The engine was tuned to optimize header performance gains
The headers are straightforward install on my X5
No other modifications were made to exhaust

Questions:
Why doesn't either TQ or HP fall off on dyno runs?
Why does TQ line fluctuate so much?
Is there a warranty?
Will there be a printed gain in HP and TQ one can expect on a stock 4.6?
How much is left for porting?
Do the collectors line up to the stock exhaust location?
Will there be a tune available to compliment the header performance?

I was going to try and answer all these questions but I'd sound like a broken record if I said "I don't know" to each.

If I have time/money I'll install these on a stock 4.4 and then my wagon's 4.6 with nothing behind the headers but miles of pipe. No cats, no m5 resonator (I'm trying to figire a way to cut and weld two small mufflers together with a cut-out just before them but I might keep the resonator for now)

I will ask Jed though. He just now is moving his shop so I'm not sure how long the response will take. Good questions however.

Plattus1000 01-09-2017 01:40 AM

BCredliner - - -

(from the man himself)

"Questions:
Why doesn't either TQ or HP fall off on dyno runs? (I assume he means looking at the dyno sheets you sent me).*


It's more of a formatting issue with the graph. *As much as I want to say my headers keep making more power beyond redline, perhaps they do. *But we stop short of redline, so not to stress the motor too much. *


Why does TQ line fluctuate so much?


The fluctuations are shift points. *We just get the car up to 4th gear to do the actual pull.


Is there a warranty?


Lifetime Warranty agains manufacturer defects.


Will there be a printed gain in HP and TQ one can expect on a stock 4.6?


We won't have this info until it's tested in your car.


How much is left for porting?


The inlet flanges are already enlarged over the factory exhaust ports on the S62/M62. *So if the cylinder heads are ever ported, the headers will already match the porting.


Do the collectors line up to the stock exhaust location?


In the case of the E39 application, yes. *If the headers are applied to the X5 chassis, it remains to be seen if it lines up. *If they don't, I don't think the final collector will be too far off. *The headers still follow and hug the bell housing. *The supplied 6" connecting pipes past the exit flange will aide in lining up to the stock exhaust. *If still too far off, I can make a different set of connecting pipes to make the connection.


Will there be a tune available to compliment the header performance?


Eventually there will be a tune but I'm not focused on that at the moment. *There are so many tuners out in the market now that will work with any set of headers."

Now it's my turn to answer a question. How much umph can be had on the 4.6 and 4.4 from just the addition of the tubes as well as the tune?

Plattus1000 01-12-2017 06:49 PM

Addendum ;
My engine is mostly stock. I can't/won't change my exhaust for the test. At most because I'm running open exhaust after the cats, I might leave them on for the dyno bit to save time and money, I might just delete the cats upon install since they're coded out anyway.

I will provide you with with the best answers to the 4.4-4.6 questions. Every car will be different for sure but I get the sense that you're pretty skeptical.

I'll enjoy getting your reaction BC.

Not skeptical at all. Just due diligence. I always do a value equation. How much improvement in HP/TQ can I expect per dollars spent.

If I have your dino numbers in your current setup and then the dino numbers after only adding headers, no tune, I can get some idea of what I might get accepting your numbers as the minimum.

Dino numbers with tune added before headers and then add headers would be OK but that would not likely optimize your application. With only numbers with a tune to go with headers I can't separate the contribution of the tune verses the headers alone.

Thus far, I an running the Dinan tune with meth so that when I am not on nitrous I still have decent performance. That means I haven't retarded the timing, it is more advanced than stock. I can't do a tune that needs more timing advance because of the risk of detonation on nitrous. That was the primary reason to add meth, synthetically increase the octane to be in safer zone. That's the long story reason for my request.

The fact that someone is putting headers on an N62. I've been longing for the Tubulare headers from SS, but they're a good chunk of change.

lo_jack 01-18-2017 12:53 AM

What software do you have to have to tune a 4.4?
I know what you need for m54...that path has been cleared by the e46 people. The e38/39 folks are less...transparent.

Plattus1000 01-18-2017 02:13 AM

I already have an amalgam of a 4.4 and 4.6 tune pieced together by Terrafantm and DUDMD.

If anything, I'll just have DUDMD tweak that for now.
These aren't cheap. The price is $5,500 for just the headers, the x-pipe and cat-delete pipes Jed sells will run another $1,200 but what you get is a lack of questions. Did I pick the right headers, will they hold up, can I salvage them if I wreck my car and sell them for good money.

I know there's some questions concerning the benifit to putting these on an m62 engine but we'll know soon enough if they produce or not.

I'd still be happy to see no gains just to know that something this beautiful is just inches from me underneath the car. I'll keep my fingers crossed for substantial gains but I am very proud to own these for their beauty also. Rolling art.

They are undoubtedly good looking. But for their cost... I'd demand significant power/tq improvements. $5500 is nearing FI costs.

Not wanting to be a debbie downer. Definitely hoping you see good results. :thumbup:

Plattus1000 02-01-2017 01:51 AM

I had a plan:
Local shop "drift office" would do a post-tune dyno so we know how the engine is running now on the amalgam tune by DUDMD and Terrafantom.

Next would be driving a few blocks to DUDMD's shop for a baseline dyno and either he or a friend you met, James (wizard behind the swap success) would help me install these headers. I'd then drive the loudest wagon ever to the other side of the state to have the cats deleted and custom work done on the exhaust, then back to DUDMD's shop so he could strap her to the dyno and see what kind of power he can pull out of the whole pkg...

Then that joker Jed called me up and said that I should drive 1,200 miles to his new shop and let him install them. He then added that Dinan was having a 50% off sale on tuning e'series cars, so let them tune headers that are better than their own e39 M5 headers. Cruel to rub their face in it but kind of a cool thought...

This would be within 1.5 weeks.

If DUDMD can save the Dinan tune to a flash drive and put my car back to the adaptations post-tune (which I'll have him save before driving down) we can then see if Dima, DUDMD can get better results than Dinan.

Dima and I had talked about adding his intake system afterwards to show yet again on another car, it would be a decent increase, especially with headers and a resistance-free (virtually) exhaust.

I'm psyched to make the journey. I've told the wife but not the wagon. That'll take some coaxing.

I'm fairly certain that the Dinan tune is a "canned" tune that is pre programmed, and is simply being loaded into your ECU. You are going to get much better results if you find a shop that has the ability to dyno tune. IMO the Dinan tune will not represent what these headers are truly capable of power wise.

bcredliner 02-01-2017 12:59 PM

Dinan tunes are based on specific Dinan mods.Tunes are done on a dyno with setup that is attached to the wheel hubs for accuracy. Dinan tunes are not so radical that they reduce engine reliability and longevity so it is likely they leave some performance on the table.

I work up a plan with tuner and dyno tech that limits dyno runs as much as possible to minimize risk of something going BOOM on the dyno. Even with a plan it is quite likely you will do more runs than planned. Unless variables such as temp and humidity are controlled I do all runs on the same day whenever possible, especially when I don't expect gains to be significant.

Plattus1000 02-01-2017 05:39 PM

I guess I'm curious what the Dinan day will be like but it should be interesting to say the least. I will let Dima do his thing afterwards regardless.

I too fear the big "boom" on a dyno. The least I can be on one, the better.

Mostly, I'm excited to work with Jed, the guy who made these. How cool is that gonna be. A fun uneventful road trip would be nice too.

I'll keep you updated.

Plattus1000 02-10-2017 01:48 AM

Update;
I ran on 2 different dyno's today to confirm but the results were, odd to say the least.

I've lost 20 hp since the tune and my afr is goofballed. I'll deal with that when Jed and I are done with the exhaust. My departure keeps getting pushed back by details but I'll leave this Saturday at the latest.

This one shows last year pre and today's post tune but the difference is about a year's time and not very impressive when you consider the higher numbers were on a stock 4.4 DME tune.
http://i326.photobucket.com/albums/k...pspca2zdbd.jpg

As to the numbers, each machine reads completely different and I don't remember the equation to get close to true rwhp but you would have to ask DUDMD about his numbers on these machines. He has his head completely around his dyno and can explain anything about it (minus that 4th readout down. That was a freaky thing to see when it happened) That, a stock 4.4 would destroy,

We were all wondering what happened there but 5 minutes later things got better. Not terribly better but better. Still wondering why the AFR wanders all over the place and why the advance is so off.

I have my stock 4.4 dyno in here somewhere. (this thread)

A readout of my 4.4 vs 4.6 on a stock 4.4 dme tune.

bcredliner 02-10-2017 02:57 PM

Dynos vary enough that is best to always use the same dyno. Results will also vary by temp, humidity even tire pressure.

There is no universal factor to gross up the wheel results to a flywheel estimate, especially with AWD because of the wide difference in designs. I think 20-25% is realistic though some dyno techs feel it is even greater. As a reference, a range of 15-17% is a common estimate for 2WD.

Plattus1000 02-11-2017 04:38 PM

Well, I'm off to San Diego for ponies!

Thought I'd pay homage to M5Jed's "Unicorn" headers, DUDMD and the guys @ Drift Office.

Tell me that doesn't look sexy as hell.

Because these are modular, the fitment and minor adjustments you make are easy. We used anti-seize to lubricate the pieces while setting it all up.

http://i326.photobucket.com/albums/k...pskxjbq0sa.jpg

The whole time, Jed kept telling me how much easier/better this whole job would be if I had either a 6 spd or an S62 in an M5. You can ask him about it. Even though there were obstcals, with the design being modular, fitting everything in was a virtual breeze. I actually slowed Jed down by "helping"

My 2.75" pipe needs to match his 3" outlets from the collectors. Tomorrow, I'll drive a straight headers car to a muffler shop down the street. Yes, I'll have some fun but at the same time, worried about either getting pulled over or scaring old people and children to death. On start-up, she currently sounds like a '60's cuda or big block hemmi. So glad I came down. I've learned so much and met some cool enthusiasts.

I think I'll pass on the Dinan "experience" I'll still drop by on my way North but not a dime will come from me. I'll let DUDMD work his magic on these headers and my car.

I might meet AquilaBMW finally, later in the week and possibly dmo84556, both of whom I missed last trip.

Yup most E39 Tourings are trashed around here. Mileage is way up, multiple owners, etc Only decent thing is you can pick up one for cheap that needs a lot of TLC and build it out to your liking

crystalworks 02-17-2017 08:07 AM

All true, but not as large as an E61... and that would add one more vehicle I'd have to do an NBT retrofit too. LOL

CleanIsFast 02-17-2017 08:10 AM

You can NBT Retrofit into an E39 as well

spadge 02-17-2017 08:12 AM

Unfortunately thats right :(
Had one before the E53: drove it 10 years, sold it last year.
I just had a look on the market some weeks ago: it was frustrating...

E61 was not an alternative for me - I don't like the design (interieur & exterieur) - looks like a pregnant whale from the side ;)
Late and !nice! looking ones (M package, black or dark grey, yellow/creme leather) E61s are very rare and not much cheaper (at least here) if compared to a F11

I ONLY like the way the Mtech package cars look. We need the size of the e61 over that of the e39t really. The modern tech stuff is of course an added bit of awesome. Including some of the weird stuff that got optioned into these things (HUD and night vision). Cost is okay at anywhere from $17k to $22K depending on mileage.

OT though, the car sounds awesome Plattus. Can't wait to see your dyno results. :thumbup:

You drive a wagon... we were talking wagons. ;) We were passing time waiting for your followup.

Now get that thing tuned and on a dyno. :D

Plattus1000 02-18-2017 04:24 PM

I know, when the cat's away.

So here's what I need to do before running on the dyno:

Figure out the distance from the exhaust port(last one on the rear, each side) to the o2 sensor for the precat location on a 4.6is engine. Add a bung, a 90° adapter for the sensor and a spacer to keep the tip of the sensor out of the direct flow of the gasses. Install all that. If you know tge length, I'd be super appreciative.

Remove my rear cats and code them out completely.

Then I can take the car to Dima, DUDMD and get to the numbers you and I want to see.

There's still the matter of the lost power last time I was on the dyno... Tune up time? New coils, injectors, plugs, filters...?

On the initial feel/sound from the headers:

Driving 1,800 miles from La Jolla, CA I can say they add to the aggressive tambour of the exhaust. I was more nervous than ever passing cops. Average driving, each shift sounds like I'm trying to race. In other wirds, before it was just a rolling build up to peak volume, now it's just evil from the get-go.

Fifth gear pulls harder, fourth is fun but 3rd is my new best friend. The headers sound so perfect.

Keep in mind, the only "mufflers" I have are the m5 rrsonator and the post cats. So getting on it is almost as loud as these pipes can get.

There's a slight vibration at idle like a 12 or 15" subwoofer is blasting @ 25 htz. Before, the exhaust manifold was absorbing the offset explosions within one single piece. Now, each explosion has its own escape route and so there's nothing to lessen the energy transfer to the engine, the engine mounts, frame and car as a whole.

I might add a washer (rubber) to the engine mounts to dampen this. I also have a little while before all the tubing has settled into place and found their comfortable homes. Once a week goes by, I'll dampen the spring clips with a heat wrap to eliminate the "twang" they can make when cold and I get too accelerator happy too soon.

That being said, I loved the feel, sound and the response when getting on it. I can't honestly say what numbers are going to show but I know it was worth it. I will be getting a muffler of some kind because the days of just cruising around and not being challenged at every stop light are gone. Every kid in Cali with a pipe wanted to test or impress me.

The "drone" at this point with no mufflers is more than most probably want. Again, no mufflers on this setup yet. I like the noise coming from a luxury wagon but there's something to be said about not showing all your cards right after a deal. I'd love BCRedliner's cutouts to a muffled system because there's also something to be said for just being the loudest kid in the room.

I found I didn't need to downshift to pass quickly but if I did for funzies, that was quicker than before and the car announced its intentions with no confusion to other motorists.

My apologies, I thought I had some clips in this thread.

This last one, Jed himself was driving. I think the grin stayed the whole trip. Keep in mind, his wagon has a full s62 m5 conversion with a 6 spd, so he knows a fun wagon when he sees one.

This one was us getting stupid. Bad video reaction time led to the shortness of this clip but it was fun.

There's truth to that. I'm still on the fence as to what badging but I'll want better decals/emblems. Theze are from Bimmian.com and are an odd font and only 1" tall... Not a fan.

Thinking about buying the 645ci (this way I get all the numbers I want) badging from BMW and replacing the ci with iT. First world problems right?

But the realist in me thinks these didn't make much HP/TQ for their cost. Hopefully this is not the case.

My experience with headers on my E39 is with SuperSprint. I've had them for ~11 years on the same car. I also added them to a 6cyl rice burner I ran for a few years.

My experience with NA on *anything* related to moving air- whether at intake or exhaust- is pretty much 'meh'. Manufacturers build in back pressure to make TQ before the motor really should. It sells cars 'cause folks think they're 'peppy'. I've surmised on my own experience that this is why many folks decide that NA intakes and exhaust are great for noise and something, but very little else on the dynos.

Similarly, headers and exhaust will raise the almighty HP numbers, but they will often rob that low end TQ. If you think ab a stock top and bottom end ability to produce power as being finite- which it is because the same internals can only make what they can make- this makes sense. Chips, intakes and exhaust really just move the power band around in the places that make us show higher numbers. They do this most often by providing space down (or up?) the power band when more air is moving through. Even the best enthusiast wants to see the #'s, so that's what we look for.

But if you take a close look at the before and after charts, you'll often see that the numbers peak at a different place than they did. Higher, yes. But most often later in the band- at higher RPM.

So I noticed that my SS headers made great power at around 3500-4000 RPM when there's lots of air to move out, I also noticed that it takes a little longer to actually *get* to that power- TQ moved later in the band as well. That's not to say that more isnt there- it's just that you might not catch up to that new 328 until you're rowing into 2nd- or maybe even 3rd. Not many stop light drags last a full 1320.

I made one early change to the intake on my NA V8 E39. It was an intake off a non-vanos V8. Yeah, I lost some low end TQ, but it showed up again with some new friends at around 3.5-4K. I lost early power in the band and moved it later. This made the 'peaks' higher. POOF! More power from a bolt on!

Enter FI. (Forced Induction)

Things got silly ab that same time once I added an SC. It may take a min to spin up. I might even tail at 60-120'. But once we get into 2nd gear and 4k or so, it's outright spooky. I did an onramp the other day in the SC'd E39, and the pit of my stomach felt like we'd just topped a high point on a country road. I was actually a little scared in my old(er) age.

Far from suggesting that the headers we're discussing here are equal to SS. They may be. That'd be fine. It'd be more than that. It'd be awesome, really.

More than that, this is a really long way of suggesting that the OP get himself some FI. Cause I've only seen one FI E39 iT and it was the sweetness of wagon function and complete balls to the wall motivation.

Also, it's kind of my hope to motivate anyone who wants headers to get them. They're super easy to install when the motor is out getting fitted to an SC. :D

An engine is a big air pump. More air in, more air out equals improved performance. It is as simple and basic as that.

More air in as long as more air gets out combined with enough fuel to create a proper mixture is first and foremost the basis for increasing torque and horsepower. This is true of any engine, naturally aspirated or forced induction. You can improve the performance of a lawnmower engine by reducing the back pressure. The stock exhausts of manufacturers don't pump up torque or horsepower, they reduce it.

Good headers are designed to have the proper tube size, length and collector to achieve better performance where there is the most benefit. If the design is good both TQ and HP will improve where and when it is best for that particular application.

Manufactures limit the tunes so they are in a safe zone for a reliable engine that stays together, generates acceptable mileage and meets emission requirements. Aftermarket chips, even used on a stock engine are more radical to achieve better engine performance and should be one of the first consideration to improve timed from A-B. The results are increased TQ and HP throughout the RPM range. Further, in the case of some aftermarket providers, such as Dinan, the tunes are specifically designed to work with their other other mods, such as low restriction exhaust, airbox etc. Increases in torque get you going faster so the goal is have the curve start higher, peak higher and fall off slower than stock curves. HP curve goal is to start higher, generally ramp up faster and higher to the optimum crossover of the curves very near where toque starts to decline. After TQ gets you going and then maxes out, the horsepower needs to keep you going.

If the only change is a more air in and out the TQ and HP curves will be similar to stock curve but be higher at all RPMs. They should peak at a higher RPM because the engine has the air flow needed to continue to generate more HP at higher RPMs when it didn't when stock but they you should never accept less at lower RPMs. In the case of an X5, I would never recommend a mod that reduces low end TQ or HP. never settle for that, don't have to to do so. Because of the weight of an X6, got to improve HP and TQ across the RPM range and increase the redline to use all the benefit of the added airflow. Because of that weight and all wheel drive improving the torque curve should take priority.

As you said, street 'races' are short. Loss of torque in those circumstances is not the way go. Until a good launch is not possible due to excessive tire spin or some other component can't take the pain, more TQ to get you going, especially with a heavy vehicle like an X5 is the best route. Except in a few circumstances such as high speed runs or something like oval racing where RPMs are always close to redline most of the time, losing HP or TQ from a standing start, light to light, a quarter mile, likely a mile will result in a higher ET. Lots of horsepower sounds good, lots of torque is what matters most.

The best mods to get the most out of a particular vehicle are exclusive to that vehicle or model if they are both the same specs. What is successful on one vehicle can be a disastrous or ineffective on another. It's interesting to hear the results of mods to other models like an E39, but we must be very careful drawing a conclusion it is the best route with any X5.

All of that is true. Let's do remember that this thread is about headers on an E39.

bcredliner 07-16-2017 05:55 PM

The OP of this thread started it about headers for a 4.4, 4.6 and perhaps a 4.8 for an X5. And, this forum is an E53 forum

Funny, isn't it? How threads ramble along and become something different than what- and even where they started. Like this thread, for instance. Not a peep about the OP's E53. Funny, too that no one's mentioned the E53 in six months.

The lifeline of a thread- like that of most things- makes relevance anything but binary.

bcredliner 07-16-2017 08:04 PM

No, not funny.

Yes, started 6 months ago. That's called hijacking a thread, bozo no no. FYI-there is an E39 forum or you can start an E39 thread and see what happens.

I don't have to start an E39 thread. We're in one. :bustingup

crystalworks 07-16-2017 10:26 PM

I'm confused...

Was just waiting for a response from OP on his unicorn header's numbers... because they might work on a v8 E53. Not that I was ever super optimistic that the cost/performance ratio would make any kind of sense. It was still a very cool set of headers and would be nice to know if they made modest power.

If it matters, I think you're not at all confused.

We are all curious about the experience of these headers on an E39 because it's the only application we have to discuss rt now. :thumbup: Hopefully the OP will have some time to update us on how they're doing in his car.

If you look back in the thread there were several members following the thread that have E53s even 4.6s that are interested in the outcome of OP project. If OP doesn't update his thread thats fine, that's his call.

It is disrespectful to hijack a thread. It is common courtesy to stay on topic. You have been around long enough to know this. If you would like to discuss e39 application the proper thing to do would be to private message him.

I'm sure the OP appreciates your guidance. But since you called him a 'bozo,' maybe he would be less inclined to consider your input. Perhaps he should never have brought up his E39 the first time. In his own thread. Tough thing to do: Hijack one's own thread. :confused:

Give it a rest. Threads move around on topics. The E39 has been a discussion point for these brought up by the OP. In the very 1st post:

We will all be probably driving electric vehicles in 10 years, but the legacy of the gasoline engined e39s will forever be a permanent part of my life.***

He even brought up FI in the E39 first. He talked even MORE about his E39 again, in *more* 1st hand detail over a year ago:

If I went VF supercharger, for $5-6k I get a kit and for another few grand in testing/tuning/parts I finally get it up and running, I'd worry about things breaking. With headers, these headers, after the install and tune, I'm not only not worried about things breaking, I am not wondering of I could have passed up on better headers.
People who've gone evolve or SuperSprint sometines question if they should have gone with another setup. I won't be doing that.

Now if the gains are above 40hp, I'm totally happy and if I can hit that mark in torque, also thrilled.

It will make the power loss from running a supercharger (50hp to run the damn thing) seem not so noticed. But, even if I decide to keep things naturally aspirated, what fun it'll be.

Wait till they get installed and I get some real numbers off the dyno and then we'll know. I have high hopes.

My goal in the entire engine swap on my wagon was to beat M5's.

Where was your disdain for topics not E53 then? Sounds like your problem runs deeper than thread content. Maybe you can look into that and discover what about this problem keeps you so distant from landing a solid point. So far, all you've offered is a mess that contradicts the content within this thread from the very start and your very own contribution a few months ago.

crystalworks 07-17-2017 02:20 PM

I was wondering where the thought of hijacking an e39 thread was coming from also, this being an e39 thread.

The OP started the thread because he's running a 4.6 and thought the headers might apply to e53's as well. Showing off a nice set of headers is always nice, but I think it may have also been to try and drum up interest in a seriously pricey mod. Not going to have much luck on that with these vehicles now being had for easily in the $5k range for a rough one, and only $12k-ish for a good one. Hard to justify 50%+ of purchase price for a mod that (I think) is going to net ~10-20rwhp on an m62b46 with no other mods.

+1

E39's from the very 1st post. I still find it funny. But I suppose I shouldn't. A disrespectful Bozo's thread hijacking from his own disrespectful off-topic thread is a very serious issue. This thread should be moved to the E39 forum... oh wait.. We don't have one of those here. Anyone who wants to discuss this should do it privately. It's just not one of the things we do around here.

I mean. Unless we already did, of course. :bustingup

Well, clearly then the only solution is to remove any reference to the E39 and replace it with the word Rainbow. I have just the visual taken from some serious chill out time yesterday. I give thee.. Unicorn and Rainbows!:

Anhelenuk 07-17-2017 05:19 PM

bcredliner 07-17-2017 07:30 PM

OP was attempting to use the E39 with headers to give 4.4, 4.6 and potentially 4.8 X5 owners an idea of what we might expect on our vehicles as far as HP and TQ gain. The intended topic of the thread is clearly about X5s.

I didn't call anyone a bozo. I said it was a--Bozo no no. That comes from Bozo the clown days. It is not demeaning to anyone. It was what Bozo said when he was explaining why you shouldn't do something. May be before your time.

I have not been disrespectful to you. I would appreciate if you would extend the same courtesy to me.

Suggesting that anyone should know better by its very nature reveals you think you know something that should be obvious to another. That's being judgemental. Placing yourself in judgement over another person is a key element to the very nature of disrespect. But that judgement is contrasted a little more clearly when it's shown to be just wrong. As it is so clearly here.

It's not that I care about whether or not you respect me in type or life. I can't. I simply don't know you. I guess that makes it difficult for me to reconcile that you might have felt disrespected by my type. Believe me, my intent wasn't to demonstrate a lack of respect. I intended to highlight a palpable disconnect between your actions and your words.
For clarity, those actions are suggesting that E39 discussion was a hijack when the OP- and specifically you- had already contributed to the same.
I meant no disrespect for anything but denying that facts aren't what the thread content shows. I do recognize and take exception to a fact laid before me and the departure from it. That's all this is.

--------------

Grasping at straws will not push away the very fact that E39's remain a constant, relevant discussion point as they have from the very 1st post. Admit you were wrong ab that and we'll have a common point from which to draw. We all know what the thread is about. The question is whether or not you can come to terms with:

1) This thread included E39's as a focus from the start.
and sooo...
2) Information and opinions (like yours) about E39's is important and germane to the topic.
which means...
3) No one Hijacked anything. (including the OP)
because...
4) No Bozo no no's here here. Thread topics change from day to day, month to month, and year to year. The thing we're here to talk about is a lot less important than the fact that we're here to talk ab them.
I should note that whether you do or don't admit your flaws here is of little real consequence. I'm not one of the people who knows you here. That lack of familiarity allows a pretty complete lack of concern for your opinion. I could care less whether your thoughts of respect and mine align. My concern of your input here stops completely at the curious satisfaction of whether or not you might admit that you were wrong about the thread content above.

The Guy that makes the headers that was referenced by the OP is m5jed on the M5 board /forum. He is easy to get a hold of if you want to find out details of the headers and what they produce. I know him because I have an E39 M5 and have bought some parts from him. I just purchased a lightened dual mass flywheel for my clutch upgrade on the M5.

bcredliner 07-18-2017 12:49 PM

There was no intention to be judgmental. Yes, we disagree but I don't think I was judging anyone.

The E39 reference by OP is what he used to convey the potential benefits of headers on an X5 because E39 headers existed and could be tested. There are lots of E39 referencing posts but that doesn't make it an E39 thread. If that is the basis for your position I understand why your call it an E39 thread and I would as well. I assume those following the thread are interested in the E39 results but the primary reason is they are interested in what gains a dyno might show from E39 results they might assume they will get on their X5 ,and, what has to be done to get them to fit when/if OP installs the headers on his X5 4.6.

I'm sure you know courtesy and respect have nothing to do with how well you know someone. I do respect and have been courteous to you. You describe yourself as a "type". I would never "type" you. IMO that means we are not unique individuals. We all have faults but it is not your place to even imply what mine are or that I am a "type". Once again, if you feel the need to respond, please do so with respect. If I have offended you or anyone else I apologize.

Since this is not good for the forum, I will do my best to not respond to you further.

Sorry for my lack of clarity. I meant 'type' as the words 'typed' on a screen, not a personality. I intended to mean that anonymous words on the screen are the furthest from anything personal.

I appreciate the conciliatory tone and I accept your apology. Please accept mine as well.

Good to know. But his results are S62 based I'm guessing. I'm curious what it made on the M62B46 the OP installed it on. The mod is cost prohibitive in my case (I've turbo'd cars for less) but the car guy in me still wants to know. :D

As I said, I'm trying not to be pessimistic... but I don't think these make HP enough to justify their cost. And I realize that is relative as well. My justification might be totally different than someone else's.

bcredliner 07-19-2017 03:27 PM

I haven't found headers that pass the test of HP/TQ per dollar spent for a 4.6.

I opted for electric cutouts a few years ago. Might consider headers if I was racing on the weekends or when I can't think of anything else that is a value added mod---just maybe.

As a point of reference, the Dinan low restriction exhaust improvements were 8HP and 7TQ . The exhaust alone was too expense for gains but it was necessary to get most out of the other Dinan engine mods. And, Dinan was pretty much all there was for a 4.6.

Plattus1000 08-27-2017 07:07 PM

All interesting stuff. Sorry I was away for so long. Let's just call it a cash flow thing.

I was waiting to install following exhaust from the collectors. I'm in that process now. No cats, a modified muffler/resonator design I'm going to try. (not sure if it's been done before)

Dima/DUDMD is moving his shop and won't be ready to dyno my car till he's opened the new store. I'll be first in line.

I'll let him tune and tweak his little heart out and we'll have data.

Again, I apologize for the vastness between my post today and last.


Oh, this happened last week;

The e53 is still parked outside, for sale. She, the wife got sick of little things getting her x5 to not be her "perfect" little rig. So she bought a volvo xc wagon and loves the crap out of it. I'm left to either keep the X5 or sell it.

The headers are designed for the 4.9 s62 but the blocks line up with the ports and with modifications, the m62's should all be able to benifit from headers not just these or supersprint.

I'm using these on a 4.6 in my wagon (plans to s/c) but there's no real difference in the geometry from wagon to SAV. A slightly more aggressive turn down at the collectors but testing in the wagon or X5 should be irrelevant.

You're all correct. It was rude to stop posting. Photobucket has me playing catchup on many years of posts. I'm getting to my bmw sites.

To all:

I'm sorry about this thread. I offered to delete it a while back or another thread that included my swap from an x5 to my wagon. I was told then not to worry since I was focusing on the 4.6is engine and it had relevance to e53's too. I guess I felt since these headers are on a 4.6 albeit a wagon e39 to be more specific, that it would be acceptable.

The delay in my posts. I can see it led to a diplomatic scruffufle. Guys, c'mon. Would you rather be reading threads about which angel eyese are best?

I'm back, photobucket can orally de-salinate the crack I present them.

I'm pushing forward, I'm sorry.

Please consume a cold beer and resume normal activities and pleasantries.

P. S. Clarabell was a much cooler clown. I remember that shite.

This was a shizz year for me financially. I got shut down on all my side projects.

I'm on my way back to comfortable so I decided to go forward:

Car is getting some body damage repaied and as soon as that's done, I'll be able to proceed.

I'm driving back down to Anaheim C.A. to see M5Jed again.

Before the trip I'll be re-doing the exhaust from Jed's Headers back. Adding extruded bungs for the pre-cat O2 sensors to 2.5" stainless piping, an x-pipe to 2 magnaflow 4" mufflers cut and welded together at one end at a 45° angle to act like a resonator, out to dual-quad tips (unless anyone wants to give me their 4.6is exhaust tips for free...?.?.?

After that, I'm off to DUDMD's house of Vroom to find my missing 20hp and tune the engine to squeeze the shizz out of these headers and see what kind of real-world gains are possible.

The suspension was refreshed recently so L.A.'s freeways won't destroy my car driving.

Should be a fun few weeks.

I hope to have answers to all our questions before March 11th, when I get back.

Side note:

I know this thread died quickly with no answers but after swapping engines, forking out $ for headers and suspension, I was pretty tapped out.

I detail boats for a living. Sometimes even I prioritize. In this case, my employees and the business got all my attention this last year.

I've been embarrassed to post anything because I didn't have much to contribute.

Still have the 4.6is e53 but now ready to sell it. Now that everything was replaced under the hood.

Don't give up on me, I haven't.

You do you Plattus. Priorities are priorities and there are much more important things than updating a project on a car forum. :thumbup:

Plattus1000 02-22-2018 01:41 AM

I appreciate the understanding. I promise to have something to add here shortly (within the Month of March)

We're done. I just drove home... The kid in me looooovveeess the noise. The adult I'm trying to act like around the authorities and my neighbors is cringing just a bit.

I can almost play with the sound like it's a musical instrument, that much control is what I'm feeling with throttle and its amazing. It is also going to get me pulled over, again and again. LoL live and learn. I don't have time to swap mufflers out before my trip so I'll be coasting past every cop I see through 3 states.

Sound clip in the a.m. I'm beat. It was 34°F in his shop. We started at 10 and finished up around 6:30.

"Dave's" Ellensburg exhaust" in Ellensburg, WA.

He did everything. I was there because he wanted to make sure everything "looked" good to me before he made it semi permanent. He was helpful, ingenious and friendly (not an uncommon theme amongst the forum members I've met).

SLIGHT modification to the spare well. lol

Always quickly finding solutions to m-sport wagons with headers and dual exhaust problems. There was possibly 10' of "trial" pipe (2.5" stainless) leaning against the wall by the time he was done.

Neat guy with a racing history (local dirt, funny and now drag) If you go, do not judge this book by it's cover-alls. He's amazing and didn't charge the moon. He's wanted to help with this build since I first thought about the swap. He's basically been waiting on me to get my shizz together. He's not alone. This is a good step in the right direction. Now, if I can tune the engine we'll finally have some frigg'n numbers to play with!

Update- (next evening) We couldn't find the extended bungs for the O2 sensors we wanted to use tonight and after a few local shops that were still open after work had nothing. WagonsHo (bimmerforums member) got dragged into it. He showed us recent pics of his beautiful roots style S/C setup for an m62 - mind blown-

I also got to see his latest of I think 4 e39 wagons. An auction buy of his that I think he got for less than a grand, heroine needles and all, with under 90k on the clock. In less than a month, gorgeous little sled and it feels fresh on Seattle's testing grounds for tank suspensions, I mean streets. Now I feel even more lethargic. He didn't have any on him which if you've met him, you might just suppose that he had 1 of every part. Because, in many cases, he would. If I knew a fraction of what he knows how to do with a car...

DUDMD is booked up and time is slipping away. I might only get the car to run on it's current tune. No hooning it up till there's some math that agrees in that computer.

Tomorrow, bungs (sourced some) possibly a muffler swap (doubtful but I'll try)

I'll be heading South Sunday, tomorrow. We got the O2's in new bungs last night. No tune/dyno yet. Might have to wait until I'm down there to play but Jed will be there so he can point me in the right "local" direction.

Safer than it looks.

All tidied up and cleared the O2.
