Big Single exhaust?

i had a single 4" on my 85 camaro. had a pretty healthy small block i had built. ran like crazy, sounded really good too. it went 4" to the muffler then two 3" out. most all of the gen 3 camaros have a single, to the muffler. just not room for duals if your looking for sound bites. i ran a spintech muffler on mine.
