Designed for Hooker Competition header back applications. This system uses 2.25-inch 16-gauge aluminized tubing to reduce back-pressure and improve engine efficiency. The system is mandrel bent to eliminate any crush sections in the tubing to help maximize the exhaust flow for better performance. Designed to be used with the Hooker Turbo muffler # 21005HKR or equivalent 2.25-inch mufflers. Fits applications with 16 gallon gas tank only.
