Engineered for 1968-1974 AMC 290-401 V8s, these Hooker Competition Headers are crafted from robust 16-gauge mild steel. The design features a long transition collector, specifically engineered to minimize back pressure and significantly improve exhaust gas flow for enhanced power.
The headers boast 5/16″ precision-machined flanges with welded O-ring seals, ensuring a consistently tight and reliable seal against each exhaust port. This flange thickness has been optimized through extensive testing to provide both durability and the necessary pliability for a perfect seal.
Each tube is mandrel-bent, a process that maintains the tubing’s structural integrity and consistent diameter through all curves. This ensures unrestricted exhaust flow, maximizing performance. The headers come with a standard heat-cured, high-temperature paint finish, with an optional Hooker Ceramic Thermal Barrier Coating available for superior heat management.
Designed for easy, trouble-free installation, these headers include all necessary hardware for a complete setup. They are carefully tuned for street performance and are compatible with factory power steering and power brakes.
