turbo-back exhaust systems eliminate all of the cats...and they sound like a v8, well thats just what this guy told me, who lives here in calgary, drives a jdm wrx, with carbon fibre hood n other stuff, and he has a turboback exhaust system, and he says its really loud. And if you want to save the enviroment then dont go with a turbo-back. Like you said you can go with a cat-bak and replace the d/p and get a d/p with a cat in it.
(anyone feel free to correct me if im wrong)
