Hi guys,

i am currently awaiting the New M Performance exhaust to arrive, and while i have my last few weeks with the stock i think I've found the sweet spot for the pops crackles, if you have DCT which i have, i am unsure if its the same for the manual probably is, if you put the car into Sport + and 2nd gear ( in full manual mode ), rev to around 4000 RPM and floor it to about 4800 RPM ( don't go to 5 it won't work ) and let off the throttle then in this rev range once you let off it pops crackles and even makes a loud whipping sound and I've found in this rev range repeatedly it happens more then often, which causes me to spend most of my time at 60kmh


just an observation give it a try ,

God i love this car.

Yeah, but in sport plus you get a really loud whipping noise between those revs, i prefer sport plus the crackles seem too artificial in MDM

love doing this too. with an aftermarket exhaust, sounds like a cannon going off

I believe what you refer to as sweet spot is the burbles at higher rpm range. Naturally, it has an higher ignition frequency so are the pitch and frequency of burbles. And the good part is, those burbles are not louder than mid-low end crackles. This is indeed a more refined kind of burble.

I love MPE from my E90 and I'm sure the M2 MPE is great. But the stock exhaust I also love besides the stock tips. My wife finds it humorous when I tap the traction button while in comfort deceleration from 3-4k rpm and it crackles and pops without being too obnoxious.

I thought MDM sounded bitchin' until I tried Sport + tonight. Holy CRAP does it sound good when you wind it out in Sport +! Not knocking those who bought the MPE or other aftermarket exhaust, but to me for a stock exhaust this thing sounds unbelievable. I love this car so much!

It sounds wicked inside with MPE in that range of 4-5k. Just need to find someone I trust to do some fly bys so I can experience from outside the car.
