I'm getting a Buddy Club Catback so my old one is up for sale, made by Revolution (?), piping is 2 1/4 I think, was on my car when I bought it. Sounds ok wasn't ricey until I put the test pipe on . Which is included up to you whether or not to use it. Price is 150 firm. I'll get pics up when I can, or look through my threads for the black 95 Integra.
