I believe my car has a 2 and 1/4" right now and I have got complaints from a neighbor when I come home from work, I have bought a 2 and 1/2" and can't wait to put it on.
Nah, what you want is those high buck electrical exhaust cut outs that Summit sells. Then you could now and then, at the right times have NO mufflers on that motor :finga:
But don't go crying here if somebody filps out on you.
