The civic has an aftermarket 2.5" exhaust on it and it sounds like a pissed bee in a tin can. I want to put it back to stock and have searched for hours about the interchangeability of civic/integra parts. My car is a 4 door and I found an exhaust on CL from an 00 GSR he said make him an offer...
Need more info, is the dealer replacing it under warranty? If so they will put in a complete engine if its cost effective. It usually costs the dealers more to rebuild the motor due to the techs time being used. The dealer then usually sells the bad motor for what they can get.
