RT 4 ROB

I'm looking at upgrading (louder) my exhaust system on my 2010 Challenger R/T 5.7L, i have been looking at a FlowMaster ForceI II Cat Back 409S, 2.5 " diameter pipe, manufacturer part number #817461 internet pricing varies from $597 to $725. Has anyone put this type of exhaust system on their car??? if so do they like the sound, any other suggestions on pipes, i like the old school muscle car sound, i have flowmaster on my 1967 Pontiac Firebird and it sounds good.

lets go Giants, Lets go Giants, yea baby 9 to 4 bottom of the 8th, three outs and Giants win Giants win!!!!!!!!!!!!!!!!!
