I have a Offroad MAC Prochamber H-pipe that was on my 03' Cobra when I bought it. I bought the cobra with 12,000 miles on it and took it off immediatly because it would not pass New York state emissions inspection with it on. The pipe was not put on the car until around 4,500 miles, so it is pretty new. It has a small dent in the chamber from a rock, but it had no effect on the sound and there is no leak etc. Highest offer takes it.
