Probably my car is pretty quite. The guy I bought it from said he did a cat back exhaust. all he really did was change out the muffler and exhaust tips. I could never find any brand on the muffler and outlets on it are either 1 1/4" or 1 1/2". So the car doesn't have much of a loud pitch to it. I plan on redoing everything from the Y-pipe back in the summertime
