Thanks for the all the compliments boys, I figured I'd get a decent response from M3 owners! I was one afterall - 2003.5 E46 M3, gone 8 months ago.
Also, with the exhaust the sound is utterly amazing. Currently Im running free flow cats as well and its sounds spectacular, but will probably take that off prior to selling. Most people might think its too loud.
Weekend: Ferrari F430 Spider- F1 - Matte White
DD: 2011 550i Xdrive M-Sport
