Hey, building a new exhaust system for my 89 IROC with a 383HSR. I plan on getting the Hedman longtube's for $150, but not sure what to do after that. I would love to go dual exhaust, but would settle for a good cat back. I heard the Y-Pipe is a b*tch to find/fab. I want something that I can tuck in because I plan on dropping it a bit.
Also I'm looking for a good quieter muffler thats not too restrictive. Cops in my area can be a pain when it comes to that, so I'd rather save some tickets.
