It was said in jest.

You did not specify a Dinan tune initially. I agree it's a good choice if retaining a warranty of some sort is of importance.

Just spent the past hour taking a ton of videos with my new GoPro with this exhaust setup. Will be creating a new thread shortly after I edit the videos and upload them to YouTube.

Stay tuned...

anyways i have the Lime Rock Edition, i was wondering if anybody knew good mods for it???
Deciding on which exhaust to choose for the track/DD. Considering the Akrapovic Full Exhaust, but if the ACM MPE combo set up has the same power gain with lesser price then I'd consider it. Does anyone know a websites comparing most exhaust from price to specs?

You're looking at similar power, it's not really an accurate comparison since one setup requires welding and is catless, and the other is a bolt on X/H pipe setup with HFC's + resonators. Personally I went with the full Akra for convenience, sound, and material, but the HFC's would add more restriction vs a catless setup in theory. It really comes down to your preference in terms of sound, and the other associated factors. Obviously test pipes is the cheapest possible mod. There are tradeoffs with any setup, it just depends which factors are most important to you.

We're going to be launching a few specials on the ACM Testpipes + Tune, as well as Akra + Tune, and the setup that epbb and the OP are running.

IMO your car sounds good

I like that higher pitched sound unique to the m3

I don't have the M Perf exhaust but I do have the OEM Exhaust Mod with ACM test pipes and it sounds pretty damn good. I'll post up a video on it on another thread

I'm actually thinking about this - MPE + AA HFC XPipe - http://www.m3post.com/forums/showthread.php?t=881329

Hay guys haven't updated this thread in a while, (sorry!). But i did get rid of my Test Pipes, still have the MPE though. I thought of two ways that might be a possible way to enhance the sound without rasp. rasp was created from my ACM test pipes & didn't like it after a while. but here are my next two options and wanted people to debate on which one is better paired with MPE.'

Since MPE is TUV certified, why not the ACM muffler mod? (nobody did this)
OR
High Flow Cat X-pipe from AA. Which deletes 200 cells from primary and 200 cells secondary and resonators are present. which is the same as test pipes, but your change the flow of air, which may alter the sound.

just wanted to know what you guys think, thanks.
