try the bassani. It does not delte your cats

 

Borla would be the closest transformation from your Camaro. Borla with Test Pipes will produce a hiss, but other exhaust produce the rasp. Borla contains really nice resonators that filter out most of the unwanted noise. Here is a clip of mine with the mods listed below -minus the spacer. The exhaust really came to life as i added mods.

Hondakiller... did you get headers after your exhaust? Could you notice the difference w/ or w/o headers? Your borla sounds really aggressive. Did you tape inside the garage?
