[More Info]
This American Thunder exhaust system is specifically designed for 1963-1966 Chevrolet C10 and GMC 1000 series 2-wheel drive, non X-Frame V8 trucks without the torsion bar front suspension. The system is perfect for the person looking for an aggressive to moderate exterior and interior sound level. Starting just after factory manifold downpipes or a set of headers, this exhaust system comes complete with a built-in H-pipe crossover and all mandrel bent 2.50-inch 409 stainless steel tubing that helps maximize the flow of the exhaust pulses for better performance and the added durability of stainless steel. The Super 44 Series performance mufflers will give any V8 a deep rumble with that classic Flowmaster tone. This system comes with your choice of three tailpipe exits, straight out the rear, side exit behind each rear tire, or dumped behind the rear tires. The system includes all hardware necessary for an at home installation. This exhaust system is covered by our Lifetime Limited Warranty. Fits both short and long wheelbase trucks.
