I listened to some of the other video clips of the new M3/M4 and I think this video in the parking garage doesn't represent the sound well. I also listened to the Akrapovic site (specifically the 1 M coupe sound files) and stock and modified it sounds great. I believe the new M3/M4 will sound a lot like this and I think that is great. The 6 cylinder will be different than the V8, but it will still sound like a performance machine.
