It all depends on your car's set-up. Different catbacks sound differently with particular headers/cam, etc. It's especially hard to say since none of the big brands out there (borla, magnaflow, slp, bassani, corsa, etc.) have produced anything for the camaro yet. For all we could know, the stock catback could sound better than all of them :( I'm OBVIOUSLY, playing devil's advocate, and it's highly improbable that that will be the case. But anyhow...
