why does it still have it's balls hanging? i would buy it if i were still using my stock exhaust....but i have a full Titanium Akrapovic....i expected more from BMW, im sticking with my mean Akra.
any idea how many the M performance exhaust adds? oh and for that price my dealer will chip my M3 for half the price, chip under warranty and it'll add 30-40hp(they claim with my Akrapovic.
