I have a 1993 del Sol Si. I believe that my exhaust just snapped off right after the catalytic converter. There is a piece that I can move up and down, and right after that piece I can feel the exhaust coming out. My question is, what is it that I need to replace? Cat-Back? The whole thing? Just need to get it re-attachted? Sorry if I'm not describing my problem that well....I know very little about exhaust systems. Any insight would be helpful.
