flow master 40 not the super series.. just the plain old 40 series.. or magna flow mufflers..
but its still gonna have that 6 cylinder sound.. i got a flowmaster super 44 on mine.. sounds rellly nice but not loud at all like my buddy with the origional 40 ...
get a free flow cat and it will be louder.. i dont have one of those.. may be why mine is quite..
