good luck, dont think it will fit. the cars just dont have the space underneith to fit a true dual exhaust, at least, none that i have heard of. and any that do fit, are complete cuztom jobs, $$$. i would reccomend a set of headers, hi flow cat, and a magnaflow, borla, flowmaster, or chambered exhaust from GMMG. the chambered exhaust is specificly for fourth gen camaros. it uses two 1969 camaro mufflers, basicly a strait pipe with dimples in it. it is the most wicked sounding exhaust for late model camaros i have ever heard. only downside, its 700 bucks last time i checked. i want one of those systems really bad. but i guess ill have to settle for my flowmaster american thunder system, full 3in system from the cat to the tips, an 80 serise muffler, and twin 23in long polished stainless steel exhaust tips. its a cruel cruel world
