OEM Mod Exhaust to MPE?

[vincE92M3]

Has anyone whose owned an OEM modified (perforated) exhaust moved onto the MPE? or vice-versa?

What were your thoughts?

It's been awhile since I have heard an MPE on the E92 M3 and am having a hard time deciding if I should make the switch.

I've had MPE, Gintani, Eisenman Race, AE, ACM Mod and a few x-pipe's.

I'd say IF your coming from an ACM Mod you'll be disappointed with the MPE unless you add the test pipes which bring out that nice tone.

For me however I personally love my Gintani Sport I have. The race is stupid loud and I believe this is the loudest sport muffler offered for the E9X. But this with Stock x-pipe sounds amazing or if you want to go over the top add the Test pipes.

IMHO it's not worth the cost; I have had the MPE for several years now and can definitely say that the sound "matures" over time, it gets louder after several thousand miles. When I installed it, I was disappointed with the sound, but loved the looks. If I had to do it all over again, I would go with a full Akra.

Thanks for the input.

I currently have the two-pipe perforated OEM mod and not the ACM with black chrome 80mm tips.

Seems like the only advantage of the MPE would be weight savings and aesthetics (great looking titanium tips).

I think I am siding on keeping my OEM mod as the MPE is also a version 1...

Is the full Akra that much louder than the MPE? I heard the Akra in person and thought it was surprisingly quiet.

Do you have any drone with the OEM mod? Especially if you are in low RPMs but high gear.

No, not anymore than the stock exhaust did.

[vincE92M3]

How about anyone who has heard them side-by-side under load?

I've watched the video where they are revving the OEM perforated and MPE, but not while driving. I don't think it's an accurate representation of the difference in sound.

db's are one thing but tone is something totally different. The tone of the MPE is unique, it has a hollow howl that it owns. I've got 2 stock exhausts in my garage and have toyed with getting one modded but it makes no sense since I already have an MPE. I've tried a bunch of aftermarket exhausts and the MPE rules for what I want (sport volume, unique exotic tone without drone)...tips are pretty awesome too. I think the perforated mod sounds good, different of course. The ACM is louder, has some drone and doesn't sound as refined to me.

Paying the premium for an MPE is tough pill, try to hook up with someone that has an MPE and see if it's worth it for you. It's a leap otherwise...tax refund?

I'd never pay MSRP for the M Performance Exhaust. I've heard it in person and ridden in a few cars with it, and it just doesn't sound like it's worth $3500-4000. I agree that it is a unique sound, but I can do a LOT of other things with that kind of money.

Even a used one at $2000 is tough to stomach. The stock exhaust sounds pretty awesome from outside the car already.

I've also heard both versions of the modified stock exhaust. The price is certainly right, but it just depends on what sort of sound you like. I decided to just stay stock and put that money towards a track day.

Perhaps I can shed some light. I used to have the perf OEM mod on my e93. Have heard and been in a car with MPE and it was very tame. But the sound is definitely unique and paired with a test pipe and you have the perfect set up. You will definitely lose some volume going from OEM mod to MPE, but you will gain a very unique tone that no other v8 has.

Right now I have a stock exhaust on my e92 and probably gona go with the MPE this time. I want a unique sound and only the MPE has it.

Very simple, I've heard both three in real: oem, perforated oem and MPE.

MPE >> OEM >>>> perforated oem.

bottomline perforated oem kills all the exotic notes our engine is blessed to have and make it sound like a much cheaper car.

Going from perforated (aka oem mod) to OEM is an upgrade no doubt.

Interesting that you say that. That maybe the first negative opinion of the OEM perforated mod that I've read and I can appreciate that. The modification does essentially change the dynamics of the muffler and amplifies the sound.

The MPE looks like it was a more straight through design, but uses perforated piping, silencers on the tips, and inconel to create the unique exhaust tone.

I have to agree. The more aggressive mod tends to cheapen the sound. I met up with someone who had it and I had the AA Signature rear only. I was thinking of going the MOD until I heard it. It sounded more raw and less unrefined. Although I am over 40 (lol), I've always appreciated elegance over loud noise. Elegance and loud is not always mutually exclusive.

I have had both and to be honest If I could do it again I would have went right to the MPE but If you personally paid for the OEM mod and did not acquire it for free then just keep it and put the money to something else.

I went from OEM to Akra Evo to MPE.
The Akra is a bit louder than the MPE. The downshifts on DCT are worthy.

The MPE has a unique sound to it. Is not boomy like the Akra and the sound changes when the car starts heating up.

Compared to other systems out there, many have stated that the Akra is pretty quiet.

I decided to go for the MPE. I'll respond back with my thoughts after I swap it sometime next week.

Personal I would listen again and actually it's quite easy to hear which sounds best ..

[Helmsman]

And thats a 2-pipe OEM only Phil? Yes sounds good...

Yeah I've watched your videos a few times! Thanks for that.

I think the difference in sound will be heard more accurately when under load/acceleration.

From the looks of the MPE up close, it looks like a straight through design similar to the ACM method, but with perforated tubing, absorption chambers, and silencers in the tips. The inconel must attribute to the unique sound as well.
