With a stock h pipe with all the cats in place, it'll sound good. Get greedy and go looking for more power with an aftermarket pipe and they'll get blatty on you. Even a high flow catted pipe is too much for a glass pack if you want it to sound clean. That's my opinion having ran them with a catted x and also an off-road x. Some people like that clapping wet fart sound though, so...it's whatever sounds good to your ears.
I like this Bullitt with stock h and magnapacks.
