anyone with flowmaster american thunder on 4.7?
I was looking at the stainless steel version for my truck and was wondering if anyone has one and what do they think of it?
Im still looking into what exhaust system I want to get and what wold be good.

when i had my 4.7 i fought the drone and just plain ugly sound, the best thing i came up with was a flowmaster y-pipe from the converters, into 3'' pipe and two magnaflow straight through round mufflers (inline, single pipe/outlet), no drone, pretty quiet idle and cruise tone, when you got on it, it made plenty of noise, but it sounded really good to, didnt have the "rasp" of other setups
