Hope it is a lot more quiet then my last system even though it had cats I think those magnapack mufflers are just way to brutal for street use. Not that I dont like a nice loud sounding exhuast I'm just sick of the BS of trying to get a sticker all the time. Even though it had a "legal" exhaust system it was still to loud to get a sticker at most places. Guess I'm turning into and old fck like bryan.
