"This American Thunder exhaust system is specifically designed for 1967-1972 Chevrolet and GMC C10 and C15 1/2 ton 2wd trucks with coil spring suspension. The system is perfect for the person looking for a moderate to aggressive interior and exterior sound level. Starting at the cross-member back, the exhaust comes complete with a built-in H-pipe crossover, all mandrel-bent 2.50-inch stainless steel tubing, a pair of Super 44 Series performance mufflers, and your choice of four tailpipe exits. One set slightly angled down to clear larger rear bumpers, one set straight out the back under the rear bumper, out the sides behind the rear tires for that classic truck look or a dump style exiting behind the rear tires level with the body. The system includes all hardware necessary for installation and provides adequate clearance for substantially lowered vehicles. The exhaust system is covered by our Lifetime Limited Warranty. If you prefer Aluminized steel construction, check out system #17654 which comes with our 3-year Limited Warranty. Fits both short and long wheelbase trucks.
