This is a stock C6 ZO6 other than a custom flomaster outlaw shorty's exhaust,, (3"in/3"out)... Personally I think if you want something LOUD that has a great rumble to it for a better price,,, instead of buying some c6 exhaust system, try this, sounds just as good as any system... Very happy with the results. And kept the stock baffles on so the zo6 so it can be turned down a little at times..... Custom zo6 flowmaster outlaw exhaust
