This Flowmaster American Thunder dual exhaust system is specifically designed for 1967-1972 Chevrolet and GMC K10, K15/K1500, K20, and K25/K2500 4wd trucks with V8 engines. The system is perfect for the person looking for an aggressive to moderate interior and exterior sound level. Starting at the Crossmember-Back, the exhaust comes complete with a built-in H-pipe crossover for better exhaust scavenging, all mandrel-bent 2.50-inch stainless steel tubing, a pair of Super 44 Series performance mufflers, and your choice of three tailpipe exits (Turndown behind rear tires, side exit behind rear tires, or straight out the back under the bumper). The system includes all hardware necessary for installation and is covered by our Lifetime Limited Warranty. Fits both short and long wheelbase trucks.
