Some options from the M3 stock "exhaust mod"

Straight through design. Don't think it'll work here, but just to give an idea: http://www.m3post.com/forums/showthr...ht=exhaust+mod

Cutting open the stock cans, taking out all the packing and covering the holes to the Heimholtz chambers. http://www.m3post.com/forums/showthr...ht=exhaust+mod

There's a better thread by the first guy who did it, but I can't seem to find it, but this gives you an idea of what can be done, and it's pretty cheap- around $200 for the M3.

Let me get this straight... You are swapping out parts designed by some of the top engineers in the world because some guys sponsored by a company told you it's "better??" But when you ask the same guy about tracking, "oh no, I have a kid now" or "I just detailed my car." or "i just got new tires."
