I have a 4.8 with a 5-speed and its loud but not the sound I'm after. I'm looking for more of a muscle car sound, i want the sound to increase as i apply the throttle too. Right now I have dual straight pipes with cats that end right before the rear tires. It sound like gunshots are going off when i let off the throttle. I do have a flowmaster that is 3 inch inlet and dual 2.5 outs in the garage but i've had flowmasters in the past and the exhaust sounds about the same from idle to WOT. I'd like to do headers and eliminate the convertors (at least same the system for inspection time) What would be the best setup for what i'm after?
