Thanks for that very informative write-up ! I'm thinking of getting the same set-up when I get my M2 in the spring. The trouble is, I don't have any possibility of hearing it for real and can't really judge the volume on the videos.
Could you possibly let us know how the sound quality and volume compare with the M-Performance exhaust ?
I live in France which is not too fussy about volume in that the annual vehicle control only takes into account the pollution, not the sound. So the danger is the police at the roadside. If I see the police up ahead and try to drive as quietly as possible, can I disguise the fact I have a sport cat downpipe and straight through exhaust, do you think ? Or is the sound raucous at all engine speeds ?
