I bought this exhaust system from a forum member a few months back. The exhaust is made for the M3 coupe not the sedan and sticks out a little, more than I like (1 inch or so).
So before I go cutting off the tips and getting them welded back on I wanted to see if anybody wanted to buy the exhaust system. It is axel back, sounds amazing, not too loud inside, just perfect.
Im asking 1000.00 for it. Here are some photos of the exhaust on a COUPE and a you tube video
