Ok so Im helpin a buddy out with his 86 camaro iroc. It has the SB 305 in it and we were lookin into an exhaust set up for it. It currently has stock headers and a very poorly made custom Y-pipe which leads to a decent cat back setup with 2 1/2 inch piping. So what hes lookin to do is get the front part of the exhaust up to par. So whats the best set up on these motors. To me he should get some long tube headers and an X pipe but at this point he wants to stick with his current catback. SO are long tubes the way to go? If he runs those then I assume that he needs to get a custom Y pipe made to adapt the headers to the exhaust. I didnt come across a compatible Y pipe. Or should he just go with some shorties and a nice Y. Throw out some opinions. Thanks
