Thanks to Prince of Persia for taking me for a quick drive in his M3 to hear the exhaust mod. It's exactly what I'm looking for, pretty quiet at idle (after warm up cycle is done), and just slightly louder at low rpms and has a great exhaust note. The aftermarket exhaust that my car came with when I imported it is just too loud for me, it's loud and agressive from start up, idle, mid range and wide open...it screams. Downtown Calgary it scares people when the throttle blips when I downshift.
I found a stock take off exhaust for sale and dropped it off at Unlimited Performance in Calgary today, chatted with the guys there, good bunch, no BS guys.
