I got some inspiration from the M3 guys who are modifying the stock exhausts to become more aggressive sounding. http://www.m3post.com/forums/showthread.php?t=720030
Anyone know what the differences are between the stock 335i exhaust and the BMW performance exhaust? Both seem like the use the same muffler housing dimensionally. I'm guessing the internal baffling and insulation is different, but by how much.
It would be awesome if we could just modify our stock exhausts for a couple bones and achieve a PE-type tone and sound. I'm sure it would be VERY popular. It might be wishful thinking, but I figure I throw it out there.
(Not interested in the catless DP + stock, or the golf tee mod sounds.)
