I've got a 2011 Quad Cab SLT Ram with the 4.7 in it. I'm looking for a louder exhaust, nothing too loud, I just want something with a grunt to it when it starts and I get into the gas. I was wondering if I could run a Flowmaster after my stock exhaust, or if I would need to cut my stock exhaust off and maybe add a second catalytic converter? Has anybody ever done anything like this? I've had louder cars and trucks before, but was too loud for the family. I'm looking for a little rumble, but nothing too loud. Any ideals out there guys?
