I'm running Fenton headers 1-7/8" pipes (keep low end torque) into a pair of 20" Cherry Bombs mounted in about the stock location. Very quiet at idle and up to 2300 rpm's. From there on up it is VICIOUS...it's the sound folks associated with the early sixes or a tornado that is about to suck up your house. Hope this helps.
