I have a custome catback exhaust I want to get rid of for a stock catback. I am not sure if the piping has been welded to the cat so I would have to also exchange the cat with it. The cat has been gutted and the piping on the exhaust is 2.5. The muffler is a canister type with 5 inch outlet. I have a silencer with it. I will do $100 plus stock parts for the exhaust. There is no hole in the piping. This will fit any 92-00 civic.
