ponchoshop, I'm with you.....currently running headers into 2.5 inch custom H pipe that tucks WAY up in the tunnel.....new heads and cam are going in as we speak and will be changing to a 3 inch x-pipe and 1 3/4 inch primary headers. Can't wait to hear the new sound....oh, yeah, gonna use Goerhlick Xcelerator mufflers and 3 inch all the way out the back....
