Hedman exhaust headers are engineered and manufactured in the USA for performance, restoration, and engine swap applications across GM, Ford, and MOPAR platforms. Since 1954, Hedman Hedders has developed exhaust header systems designed to improve exhaust flow, increase scavenging efficiency, and support stronger torque and horsepower across the RPM range.
Designed for proper chassis clearance and optimized exhaust performance, Hedman headers are available in multiple configurations to suit a wide range of engine combinations, performance goals, and vehicle applications.
Headers improve exhaust flow compared to restrictive factory manifolds. This can improve horsepower, torque, throttle response, and overall engine efficiency depending on the vehicle and engine combination.
Yes. Hedman headers are engineered for specific engine and chassis combinations to ensure proper fitment and installation compatibility. Always verify application fitment before selecting a header set.
Some installations may require reducers, connection pipes, or minor exhaust system modifications depending on the vehicle configuration and header style.
