mufflers or no mufflers??

yup...every guy around me with a v8 all run the same exhaust being magnaflow....one guy even tried to tell me flowmaster is **** and that magnaflow outflows them...If my eyes were closed when he started up his firebirn for i swear i would have thought it was a chevy beretta with a whole in the exhaust....the only thing i have ever heard magnaflows sound decent on is some imports like 350z's, but they only sound good because they enhance the import fart sound...ill never go maganflow...sorry mario andretti
