it does sound great when i'm on it, maybe that's the answer...just get on it more...likely if i swapped, it would be used for used, in which case i'd probably be taking out money. the used oem exhausts i see are almost free....that is not the main goal however.
do people really notice any performance gains with these exhausts? i see the claims, but in the real world is there any difference? the only e92 m3 i've ever driven is the one i own....with the exhaust already installed so it is my only reference point.
