Since 1954, Hedman Hedders has been a trusted name in high-performance exhaust systems. Founded by Bob Hedman in California, the company built its reputation around precision-engineered headers designed to improve flow, reduce backpressure, and unleash real horsepower gains. Each set of Hedman Hedders is manufactured with tight tolerances, ensuring consistent fitment across classic muscle cars, modern performance builds, and engine swap projects.

Today, Hedman continues to deliver American-made performance through advanced CNC mandrel bending, 3D scanning, and precision welding. Their product line covers long-tube, mid-length, and shorty headers, as well as LS/LT swap kits, gaskets, reducers, flanges, and hardware—available in raw, painted, or ceramic-coated finishes. Whether you’re restoring a classic Chevy, building a custom LS swap, or chasing every last horsepower on the track, Hedman delivers the perfect balance of legacy craftsmanship and modern innovation.
