take it back and get them to adjust the exhaust
did u just get the muffler put on - or is it a full catback system?
im getting S12 + 2.25" catback + 2 hotdogs + hi-flow cat - put on today
im hoping the hotdogs will keep it nice and low sound without and fart or rasp - my mechanic will adjust the setup if it sounds shit tho =)
