Man, they had that feature in the old old mustangs. My friend who's into muscle cars told me that when they used to drag, he would pull a lever inside and the valve comes open and you can hear that **** a mile away. And when the race is over, you just close it up so it won't be so loud. But good idea tho for the e46. haha. Be the first for the e46 guys who ever does it.
QTEC Electronic Exhaust Cutout?
