I bought a pair of ceramic coated long tube headers from Flowtech, a 3" x pipe kit, and two dynomax race bullet mufflers. Because when you have a '74 truck in CA, you wanna stick it to the smog people as much as possible. And the sound from the 454 should be pretty glorious. With a couple friends, a full machine shop and a Millermatic 350p at my disposal, by the end of the weekend, ScarJo should be sounding real good.
