A friend of mine is getting ready to put exhaust on his 00' WS6 Firebird. I have a flowmaster catback on mine and he'd like it to be a little quieter than mine. Does anyone make a system that has a good sound but not too loud. Thanks Guys

 

I have Magnaflow and it's pretty quiet with a nice mellow tone. Even at higher RPM's it's not extremely loud. Corsa makes one of the best sounding exhaust systems but they are pricey and a little louder.
