my baffles were starting to go and in high revs i was starting to get that old gm 6 cylinder rumble that sounds like shit. i picked up an E36 M3 muffler for 100 bucks and it looks better, sounds smoother and is a tad louder. a guy at work had virtually the same car as me and it didnt make any sound diff whatsoever so it might be because of the M50 manifold swap and debaffled intake i dunno
