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.
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.

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.

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.

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.

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;



There's supposed to be a picture of the rear of my car with an indent of someone else's pickup truck grill. Good times.

But the realist in me thinks these didn't make much HP/TQ for their cost. Hopefully this is not the case.
Partly yes to the 1st part, not sure on the 2nd part. Life got in the way. I'm still pushing forward.

All new suspention, all. Powerflex bushings etc.

Doing follow-up exhaust work now and plan for the dyno in 2 weeks.

Sorry...

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