well after a week of waiting i finally got my M3 back. a local all bmw tuner, stett performance, did my a custom one-off stainless steel exhaust from the headers back (secondary cats delete.) everything was mandrel bent and tig welded. i only have time to post this one video, but i'll post tons more pics and more videos tomorrow. its very loud and has GREAT tone. hope you like! i sure do!
