Best exhaust upgrade for e53 3.0???
 

From user experience what's the most budget friendly exhaust upgrade you've done for the 3.0?

N62 4.4i mufflers from the junk yard. Drop in, much better sound, dirt cheap.

Cool! Something else to my wanted list.
4.4i exhaust. :bmw:

interesting lol


It is quite a difference

Note that the M62 mufflers appear to be identical to the 3.0i mufflers. Even the 4.6is. So those are a cosmetic upgrade for better tips, but no change in sound.

The facelift 4.4i mufflers drop right in.
You can also do the 4.8is mufflers (what I have), but those take a little more effort as the flanges are a different size.

noted thanks for the heads up, if you have any spare ones let me know!

I have a set of 4.6is mufflers if you are interested. I just put my dinan exhaust on last week.

That would be great, feel free to shoot me a DM? Would you suggest I run an xpipe with this configuration too and do the res delete?

Great upgrade!! Should have a bit more aggressive tone as well.

Thank you MrCouch was kind enough to sell me his 4.6is mufflers which I'll swap out for my 3.0i ones with the addition of the magnaflow xpipe, looking forward to it as I can't find a video with this specific configuration

I put 4.6iS mufflers on my 3.0i a few years ago, and they won't make any difference in noise. I would like to do a resonator delete/X pipe as well someday, but it's low on the priority list. The 4.6iS mufflers do look a LOT better though.

Yeah you definitely need to remove the resonator to change the tone. The x-pipe will help balance out the back pressure, and create better flow.

Headers is the only true performance upgrade everything else is tone. As mentioned, the V8 muffler will provide a better experience without resorting to headers.

I agree with this, I'll keep you posted next week when I get this mod done, really excited lol

I've heard the same thing, budget wise this is a good mod for the time being at least

Found a clip online actually, this is what I expect it to sound like

https://www.youtube.com/watch?v=gNBC...l=PapyVaklinov

Yeah, that's the advantage of the N62 mufflers. Just enough more sound to make a noticeable difference. Not enough to be annoying.

From the video I posted above that I located online it seems like it's the perfect balance of sound, at least for me

Yeah, if you want to do a resonator delete, that changes things. I didn’t want to touch the X-pipe.

that's the plan stan, better flow and increased MPG, might as well

received the V8 mufflers today, plan is to polish and clean them and tomorrow I'll have the work done along with xpipe installation

cheers :)

Something that I need clarification on, I have the 3.0i E53 without the sports lip bumper option, from experience the 4.6is mufflers should be able to still fit correct?

Did you have the sports bumper lip, I don't have that on my 3.0i so I assume they 4.6is mufflers will still have plenty of room to clear on the bumper inserts?

Yes, they'll fit fine. The only thing you have to do is pull out the insert that goes around the muffler tips. Ideally, then install the V8 version (it's the same for a 4.4 or the various "is" models), but that's not actually necessary.

Yep, like Nick said, you just need to pull off the trim ring. I left it off and never acquired the correct one from an actual 4.6iS because you can't even tell anything is missing. It looks perfectly fine without it.

Sorry, one caveat though: you will need to loosen the rear bumper to install the mufflers. They flat out will not go on without moving the bumper back a few inches. And to do that, you need a T55 star socket (IIRC) so please make sure you have that before you try to install it. I had to go buy one and it took me a bunch of extra time to figure this all out.

Ok thank you I was reading this forum below and he has the same bumper trim as myself and for some reason by eyeballing it I figured the 4.6is mufflers wouldn't fit (I bought 4.6iS mufflers with the oval chrome tips)

https://xoutpost.com/bmw-sav-forums/...-retrofit.html



Thank you so much I'll confirm on this to be sure, I did order the 4.6iS rings and have them already



I'll be sure to relay this to my muffler guy before he installs, thank you very much

Here's my install day:

https://xoutpost.com/1220991-post15141.html

I was able to wrestle the mufflers in, but moving the bumper would have made it a lot easier.

This makes me feel better thank you kindly!

I'm basically doing the same with said xpipe, I believe the proper size for the 3.0i is 2.25

According to BMW the 4.6iS trim doesn't fit the 3.0i which is strange to me but I'll look it at later this evening when I pickup the car.

Doesn't fit based on what? RealOEM? That's irrelevant.

Heading to the dealer shortly and will keep you posted, I'm pretty sure their wrong lol

Yeah I never actually bought them but it seems like the dealer is blowing smoke.

funny thing is they fit just fine, bad news is now my AC doesn't work after they did an AC recharge, going to call them tomorrow, unreal by them and also not surprised

I mean, the parts catalog will say that they don’t fit. They’re the wrong part for a 3.0i.

Good luck with the A/C. Tracking down A/C issues is always fun.

What's funny is I called the tech over, told him to put the trims on, told him they would fit, comes back to me and tells me they didn't fit, I proceed to pick up the car yesterday and I put them on myself LOL

Compressor and water valve are bad so that's the culprit of the AC issue :)

:bustingup
That sucks. But not as much as a bad evap.

Yup, taking her during lunch and gonna work from there :/

lovely Friday I must say hah

buddy from muffler shop quoted me 250 for xpipe and v8 muffler replacement, said this is no problem and has worked on my older german cars before, he loves the E53 :)

Wow, great price. I would go X pipe too. My '83C10 has one with dual Magnaflow mufflers. The X5 muffler is in great shape externally. Wish it had more rust or a hole so I could upgrade.

Yeah he recommended magnaflow 2.25 for the 3.0i models which I bought and there are only a few videos on youtube that show show what it sounds like with a V8 muffler replacement, regardless should be better for the engine and also look much cleaner in the rear

Magmaflow with x-pipe.
https://www.youtube.com/watch?v=s7Io4esUKVs

I'm familiar with Magnaflow on V6 sound. I've owned two. A Nitro 3.7L and resonators. A '96 Jimmy with a 4.3L single pipe all way out. The longer the muffler, the quieter. Above 2300 RPMs, they really wake up sound. Idle and slow speed sound is satisfactory.

I will say that the magnaflow mufflers have not been a good experience for me on various BMW I6es. I've tried a lot of Magnaflow combinations and they were too loud and too drony down low. If you need a muffler that's loud enough up top and not bad on the street, I have yet to find anything that touches the Dynomax Super Turbos.

Edit: This does not apply if you keep the center resonator, which seems to do nearly all the muffling on E53s (and also at least the I6 E39s).

yeah for the price and mod cost a simple magnaflow xpipe and V8 mufflers on a 3.0i will be enough, especially for a v6 :D

Soouper Turbooo’s… This member here knows their mufflers. I’ve heard these on sooo many different applications.. Sounded good every time. LoL.. :rofl:

It drives me crazy that all the useful variants are mild steel, but I have yet to find a better choice. And at this point, I've kind of given up. Nothing like rebuilding an exhaust multiple times to end up where you knew you should have started.

I'll still git a bit more of a growl however with my setup right?

A huge fraction of the muffling is done by the center resonator that you're replacing with an X-pipe. The 4.6is mufflers won't be louder as I understand it, but the resonator delete will be.

True, think it's overall a positive upgrade for better flow too and as far as aesthetics the car will look much better too

Oh yeah. I didn't really care about extra noise. I just couldn't stand the tips. Fixing the hideous turn downs is a huge plus, whether you swap tips, mufflers, or whatever. And the x-pipe should flow a little better. (Mind you, I don't think that higher flow exhausts will make a meaningful difference until you change the headers. That's where the opportunity is.)

Agreed, I really haven't messed a ton with the X on mods like this so little things for example the xpipe go a long ways for me, looking forward to it

There are very few exhaust systems that sound good on a ‘91 Civic, or any Honda for that matter. The Japanese systems sounded great, however they were pocket breaking in those days. But, 2 1/4” pipe with a Super Turbo allowed that little 1.6 to showcase its tone nicely. Add a glass pack for resonance, and the sound was almost identical to the Japanese systems. This is just one of many applications I’ve experienced. Great Muffler indeed!


Definitely! Deleting the resonator will most definitely amplify the sound. The x-pipe will just balance back pressure.

Most definitely! I didn’t even own my X yet, and those mufflers and tips had to go! LoL.. :lmao:


When I did mine, I upgraded the pipe size as well. That along with the CAI did produce a bit more power under acceleration, but nothing spectacular. Looked and sounded way better though.

The headers though.. Dayum! The X is one of the only vehicles I have slapped headers on and was shocked with the results! The sound, power, the whole 9. Those stock manifolds really do neuter the M54.

getting the work done tomorrow, excited!

minor small increased rumble, tips look amazing and drives great!

Sound clip? Pics?

Worth a shot here but anyone have an older remus, supersprint exhaust they'd want to get rid of? I don't really want to do a muffler delete as from the sound clips it sounds horrid on the 3.0i. Any suggestions would be greatly appreciated, all I've done thus far is xpipe and 4.6 mufflers installed.

Just looking for a more deeper raspier sound without going crazy spending

Did you remove the resonator when you installed the xpipe?


E53 RiPPeR
XOuTPoST jUNkiE
ReVELaTiON 22:21

yup, installed the magnaflow xpipe and def sounds great on a cold start, unfortunately with the e53's we can't do the golf tee mod lol but other than that I'm really happy with it, since I have the prefacelift model it's really hard to get a good exhaust sound without spending a lot of money for the 3.0i

assuming there is not much I can do besides upgrade mufflers and straight pipe?

The issue is the limited space available. The stock mufflers are compact in my opinion, and the plumbing along with tip placement just complicates things even more.

That is why it is difficult to replace the mufflers with a high flow type, with a more aggressive sound. I am all for hearing my power plant scream, but do not run straight pipes. The cats alone are not enough to refine the tone.

My suggestion, find the smallest, and I mean the smallest high flow mufflers available. Get them installed and worry about the tips after.

ReVELaTiON 22:21

I'll see what I can find, right now I have MrCouches 4.6 mufflers in there and they look great with the tips, any suggestions on brands?

It's important to note that the 4.8is mufflers are MUCH louder than the 4.6 mufflers (which are the same as the 3.0i mufflers, except for the tips). If you want some extra noise for low effort, that's probably your best bet. I believe that the 4.4 N62 mufflers are the same, but don't know that for certain.

I suppose, not really feeling like it would make a huge difference tbh on a v6, my theory was smaller mufflers and possibly more stainless steel options but I could be wrong, such a shame they made the v6 so silent

The I6 is anything but silent, trust me on that. With cats and stock mufflers the sound will definitely be deadened.

I’ve been told I can be heard miles from said listening location LoL.. Try and find super small straight through design aftermarket mufflers. It’s your best shot.

I have 4.8 mufflers on my 3.0 and the noise difference is dramatic. To the point where non-car people notice. Combined with your resonator delete, it'll make a real difference.

I referred to this thread when looking at all options and heard the sound clip, didn't really make a huge difference than how mine currently sounds but I'll keep a lookout for any 4.8 ones for sale

https://xoutpost.com/bmw-sav-forums/...eo-inside.html


"mrbmwx5 has put 4.8is mufflers(left and right), each of the muffler is list priced at $819.40(see link below). If you are buying these from dealer, it will cost you over $1600 +labor. You still will not have as good sound as you will with Eisenmann or Remus mufflers for less price. Unless you can get some used mufflers, its not worth it"

Or you could get something like this..

https://www.dynomax.com/ultra-flo-st...tered-596.html

I am positive you’ll hear a difference with 2 of these. And the muffler body is only 12”. Might work. :dunno:

was leaning towards something like this, I know it won't sound ideal but I already have a similiar setup

https://xoutpost.com/bmw-sav-forums/...deo-4-6is.html

That is pretty much what I’ve been suggesting. The 3.0 will have a different tone compared to the 4.6, but it will definitely have a stronger tone than the stock mufflers you have installed currently.

If you’re looking for sound, this is the right path.

good point thanks for the suggestions everyone, greatly appreciated!

can anyone recommend dual muffler tips they liked?

Was thinking the 2 options below :

https://www.amazon.com/Yonaka-Outlet...omotive&sr=1-2

https://www.amazon.com/Vibrant-Perfo...0-4513d670b6bc

Also similiar engine and idea that I want to do
https://www.youtube.com/watch?v=2f4m2HuPujM

I have been considering electronic cut outs for a long time. You get the quietness your passengers and neighbors enjoy, but can open it up when you get away from people and let it roar. And you can fine tune how far you want the cut outs to open just by turning a knob on your dash.

for the vibrant resonator size does it matter if it's 2.25 or 2.5 for the 3.0i, I know the xpipe I have right now is 2.25, just curious?

I believe when I swapped the 4.6 mufflers and put those on the 3.0i those are 2.5 and the guy at the shop mentioned he had no issue welding them on.

The best was the n63 upgrade. Beat exhaust note! My wife literally called in therapy!

(For clarity we upgraded the 3.0i to a 50i X5)

The second best: n55 in the 35i. That one I can use the bimmerlink app to open the second exhaust pipe and it sounds very nice.

Def look into whatever mod it will take. I'm looking into adding a vent on wife's F10 (535 x-drive) becusse she doesn't have the exhaust flap I do it just must have a quieter muffler and both tips active.

305 HP and gets 25.5 avg mpg! Over 50% better than our 3.0i and 35% better than I usually get with same motor in my X5.

Back to topic; for a manual option, installing a plumbing fitting with a simple ball valve was the easy option. I think the guy used a 1/2" or 3/4" ball valve. I can't remember what he uses as the bung, because cast is hard to weld and stainless isn't a cake walk either

thanks buddy, I'll look into that, I was hoping someone would just say you can use the 2.5 vibrant resonators and I should be fine lol found a good deal on fb marketplace

For a preview pull out one of the post cat O₂ sensors.

Yeah not trying to put a damper on the thought of doing a proper replacement resonator just sharing a thought based on a YouTube video I saw recently and my own desire to pump up my wife's F10 muted exhaust.

She went from X5 e70 50i with the most amazing "exhaust note therapy" to almost Lexus quiet F10 exhaust.

You can hear the exhaust note on heavy throttle and it even sounds good. Just sounds much good-er on my X5 with the exhaust flap open.

this is basically what I want to do but with the 3.0i, I already have an xpipe installed and the 4.6 mufflers on my E53

https://xoutpost.com/bmw-sav-forums/...deo-4-6is.html

Better yet! You already have a perfect spot for the vent. You can add a solenoid control vent and you can start with a bigger hole and add a reducing insert if it's too big.

My first test with the open flap I just unplugged the vacuum line and put a screw in it. I could manipulate the flap open/closed manually and I figured out that 3 or 4 hours is the limit before it gives me a headache. Fortunately I discovered I can perform the function with bimmerlink so I set it to auto for freeway driving and open the rest of the time.

simplicity is key here I'm not trying to break the bank but I appreciate the suggestion lol

Please share what you end up doing.

Thank you sir

the only thing I'm worried about is drone but I think with these Vibrant resonated mufflers it's meant to eliminate that

I don't mind the drone unless I drive at least a couple hours straight

Fill me in on your setup? I have the xpipe currently with 4.6 mufflers on the 3.0i

Plan is to install the vibrant resonated mufflers in place of the texas size mufflers and add quad tips

not applicable to my current car. I have stock 35i E70. Has two exhaust tips one has a shut off flap.

ahh yes that doesn't help lol

When I had the 3.0i I was wanting to do what your are doing

the only good thing is if I don't like it we can put the 4.6 mufflers back on lol I have not found a video of anyone doing this either Andrew, at least on the 3.0i

If anybody did some cool muffler 3.0 option it was [mention]Happy [/mention]

He uploaded videos of drive by to show off his "exhaust therapy"

correct, he also upgraded the headers/cats too lol he went all out, not sure if I heard a sound clip of his either

I'm so hesitant on doing this but we will see the turnout :dunno:

picking up the car this afternoon, hoping it will sound good!

update, was wayyyyyy toooo loud and annoying, had him weld on the normal 4.6 exhausts and left it how I had it....

returned all the parts and got my money back, got new spark plugs installed and a small alignment done too, going to just keep the exhaust system the way it is!

Wow that's a setback. Bung with water valve always a future option.

Hehe.. I was telling you. The I6 can scream depending on the setup. And trust me, my setup is still 10X louder than what you experienced LoL..

Last year I took my X5 to a DYI shop to use a lift. The front shaft guido was replaced. While I had it up in the air, a tech came by. He stated he has seen a lot of BMWs there. A lot of them for exhaust work. He says they come back to remove mods and install back OEM exhaust. Or another change is made.

full refund, the shop owner is a super nice guy and didn't charge for the trial run for my exhaust idea, the wheels are amazing and fit perfectly thank you!

it's all trial and error, very few ppl have done total exhaust work on 3.0i besides xpipe which I have, regardless I still love my car and will continue to drive it to the ground :)

I'll try to grab a picture of the new wheels sometime this week as well!

I feel ya. I only put about 100 miles per month on my X these days so, it’s more of a toy than transportation. However I do daily drive it, but my trips are very near to home.

There is supposedly close to 500 flywheel horsepower. So, I am sure that has dramatically affected the tone. But, it sounds really good, that’s why I haven’t changed it. But, it is definitely very LOUD. :D

I was able to find 2 super turbo mufflers for 30 bucks a piece on FB marketplace brand new lol, haven't pulled the trigger yet but this thread came to mind after my epic fail with the vibrant resonated mufflers

Ok, since you deleted the resonator and replaced it with an x-pipe, if you did run the super turbo’s. It won’t be loud because, you’ll be deadening the M54’s sound with 2 mufflers vs 1, with cats. But I can assure you, as far as my taste is concerned, they should sound better than stock.

But again, every application is different. So meditate on it. But… $60 bucks for 2, in my opinion, great mufflers, I dunno… :dunno:

I wouldn’t think twice to run it on my setup. Resonator delete, with an x-pipe, and super turbo’s with headers! ALLL-DaaaaaY…

my thought process is it will still sound better than the 4.6 mufflers since they weigh a ton and are huge lol good points

remember I'm not trying to have it LOUD like yours lol

what upper intake tube did you buy to fit your cold air intake, I just swapped my OEM cold air intake and threw on one but I'm thinking of trying to find a custom upper hose

The Super Turbo muffler isn’t all that small either though. I would look up the specs and make sure you have clearance.



LoL.. You shouldn’t have to worry about that. My setup is quite a bit different than a stock E53. The dual muffler system should definitely deaden the sound, while keeping it tuned vs just using resonators.



I have a very large supercharger connected to my intake manifold LoL.. But before I had my blower, I had an aFe cold air intake. It worked great for what it’s purpose was!

I love my X5 exhaust upgrade.

(Not exactly the most economical).

(This is my 2011 35i that replaced my 2001 3.0i)

I do love the exhaust note. Wife calls it exhaust therapy. I agree.

Here's another where I rev twice and open the exhaust flap for the second rev.

https://share.icloud.com/photos/0ca4...pAPL2363_ApwQw

You'd think you can modify the 3.0i exhaust to match the 35i. You won't get quite as burly of a note but the first video above is just idle and it's the same basic engine when turbo not spinning. Wonder what it would take to retrofit e70 exhaust to e53. (thinking junk yard grab).

thanks for the suggestions, I will keep you updated and this week I'm doing the wooden trim wrapping to gloss black and upgrading to the xtrons radio unit first

Happy now I'm conteplating Vibrant Ultra Quiets lol

I did measurements and you were right the Dynomax Super Turbos will not fit

Vibrant Ultra Quiets would fit much more better

https://youtu.be/LR8T_E7o_fY?si=AWBohAyOiKj_5dSV&t=281

I had a feeling. It’s pretty tight back there.

Those Vibrant Ultra Quiets are pretty much what I suggested in the beginning, just in a different brand. I don’t think the brand would make much of a difference being that their the exact same design. But, you never know. The Vibrant brand seems to be a good quality part, although I’ve never used it. I’ve used the other brand numerous times.

I got two Super Turbos to fit in the stock space in the back of an E30. I would be very surprised if you can't get them to fit.

The standard length for a Super Turbo is 14", which is only a quarter inch longer than the Vibrant Ultra Quiet.

Don't forget that the mufflers don't need to be flat, also. You've got a bunch of height in there to work with if width is an issue.

that does sound nice, I have a theory now that my whistling sound might be a crack in the valve cover gasket which makes me want to replace this as I haven't done it in awhile, have you heard any reviews on the aluminum ones?

I'm leaning towards just going the BMW OEM, those usually already come with the gaskets and such installed on them too if I recall correctly.

I used the OEM from FCP. I'll be sad if I have to replace it but if even lasts a couple years will be worth the $390 savings

yeah that's the only thing that's making me go the aluminum route lol

Andrew I finally found a video of the same exact whistle btw, could be the alternator?

https://www.youtube.com/watch?v=nXSzp2Ix_Sk

Definitely can be. Easy to test with a cold engine since no coolant pump pull the serpentine belt and drive a course you can repeat the sound.

Mechanic stethoscope can narrow down sounds such as this.

tested the alternator and the voltage is good but diodes are broken which could explain the turbo whistling sound, getting a new alternator Friday as this one is the OEM that has lasted 20 years lol, will report back!

Broken diode is the usual cause of your symptom.

Alternators generate three phase electric AC and that's converted to dC though a 6 diode bridge rectifier.

When one or more of the diodes fail (usually open), you'll get lumpy 2 phase power. This will give bumpy torque at the drive belt causing vibration.

It can also cause electrical interference that you can hear in the stereo.

this explains my speakers randomly getting low at times on certain sides of the car, I'm getting the Valeo style 12v 140amp alternator installed Friday

I'm just surprised the voltage is still good after all those years but oh well I guess I got my money's worth


Sidenote: got the classis engine failsafe error tonight after leaving the gym, turned the car off and waited a bit to restart, started her up and bam everything ok, I think this might be a good sign alternator is starting to take a shit lol

alternator was the cause of the whistle noise, replaced a few belts as well, running like a champ now, however on the prowl to maybe sell since I think it's time to move to an X5M :)

so I found mint condition 4.8 mufflers, might pull the trigger on it, I can sell my 4.6 cans on here if anyone would be interested?

can you post or dm me a clip of your 4.8 mufflers on your 3.0i?
