High flow cats are just noisy. Cat bypasses are obnoxious. Even headers add to the rasp. My car never sounded better than when it just had aftermarket mufflers and everything else was just stock. I just took off the muffler bypasses recently because I got tired of not being able to use my cell phone.

I would leave the headers, and especially the cats, alone.... People take it for granted but the cats do a lot of sound deadening. These engines don't sound good raw.
