well i replaced the stock res with a magnaflow res and replaced the stock mufflers with magnaflow mufflers (got them all from stazi). it sounds great. no rasp at any rpm and gives a real nice throaty note when you get on it. i heard my friends svt with a bassani exhaust, gutted cat and headers and it was very raspy. and i mean VERY. but he just got a highflow cat and magnaflow res from stazi and it sounds great. loud as all hell. it still has a little rasp on the top end but hey, what can you expect with that setup.
