My wife took her 2012 R/t to the local performance shop who has complerted work on some of my cars concerning exhaust systems so I like them. She wants to get a little more growl out of the stock system. We inquired about magnaflow mufflers. He took a look and suggested taking out the stock mufflers, running an "S" pipe and leaving the resonators and the rest of the system in. Has anyone done this before? How loud would it be? She doesn't want it to sound like a drag car. I'm sure giving it more flow will increase power but.....
