So I purchased 2 Magnaflow 10416 mufflers to put on both sides of my spare tire well. After thinking things over and talking to the exhaust shop I figured this will not give me the results i'm looking for. Still would be overly loud and annoying because these mufflers aren't really true mufflers...more like bigger resonators.
So I ordered this catback system from Umnitza:
This was made for non M E46's with M3 rear bumper but should work with my car.
