The American Thunder Crossmember-Back exhaust system for the 1966-1967 Ford Fairlane is constructed from 2.50-inch mandrel-bent 16 gauge aluminized steel tubing to maximize the exhaust flow and comes complete with an H-pipe crossover to equalize the exhaust pressures and eliminates backrap on deceleration. The large case Super 50 Series performance mufflers provide a deep powerful sound and maximum performance flowing into the mandrel-bent tailpipes. The Super 50 mufflers also incorporate built-in resonators keeping the interior resonance down to a minimum. The system is finished off with large 3.00-inch angle polished stainless steel tips and includes all necessary parts, hardware and instructions to complete the installation. All aluminized steel exhaust systems are covered by our 3-year Limited Warranty.
