guys i want to sell this exhaust or either trade for another aftermarket one for a 180sx - one that is more quieter. I havent measured the piping but visually it looks to be 3.5" as compared to the zorst on the 33 - 3", it definately bigger. Unfortunatly, it does has a dent on the bottom of the muffler although doesnt affect the sound or peformance. Its a straight through cat back variant hence the loudness. Im asking for $400 or trade + cash adj. Pics will be up soon, hopefully.
cheers
