This American Thunder exhaust system was specially designed for 1973-1974 Chevrolet and GMC C10 and C15 1/2 ton and 3/4 ton 2wd trucks and is perfect for the person looking for moderate to aggressive interior and exterior sound levels. The system is a cross-member back exhaust complete with a built-in H-pipe crossover, all mandrel-bent 2.50 in. aluminized steel tubing, a pair of Super 44 Series performance mufflers and your choice of tailpipe exits. Either dual out rear under the bumper for a muscular look or dual out the sides behind the rear tires for that classic truck look. The system includes all hardware necessary for installation and is designed to accommodate both long and short wheelbases, with either an automatic or manual transmission and provides adequate clearance for substantially lowered vehicles. The exhaust system is covered by our 3-year Limited Warranty. Notes: Does Not include exhaust tips or header reducer cones. This system is not emissions compliant on vehicles that were originally equipped with catalytic converters.

  • Includes Hangers and Hardware for Installation
