Hedman Hedders is one of the most respected names in high-performance exhaust solutions, known for producing top-quality headers, exhaust components, and emissions-compliant systems for hot rods, muscle cars, trucks, and racing applications. Established in 1954, Hedman has spent more than seven decades perfecting the art and science of exhaust flow, earning a reputation for American-made durability, innovative design, and proven horsepower gains.
From the beginning, Hedman’s mission has been to engineer headers that maximize scavenging, reduce backpressure, and increase overall efficiency, resulting in real performance improvements across the RPM range. Their catalog features long-tube headers, shorty headers, mid-length designs, tight-tuck configurations, and race-only applications, each built with precise fitment to match specific engine and chassis combinations. Whether you’re building a classic small-block Chevy street machine, a modern LS-swapped hot rod, or a purpose-built drag car, Hedman Hedders offer solutions designed with performance-first engineering.
Every Hedman header is crafted using mandrel-bent tubing, heavy-duty flanges, precision welds, and high-temperature coatings to ensure long life and consistent performance. Builders can choose from uncoated, satin-black, ceramic-coated, and HTC high-temp finishes, all designed to withstand extreme heat while maintaining a clean, show-ready appearance. Hedman’s coatings not only improve underhood aesthetics but also contribute to reduced heat soak and increased exhaust velocity, yielding more efficient power delivery.
Hedman is also a leader in emissions-compliant exhaust components, offering 50-state-legal header options designed to maintain O2 sensor locations, catalytic converter operation, and factory emissions standards. For performance enthusiasts who want more power without sacrificing compliance, Hedman provides engineered solutions that balance modern regulatory requirements with classic hot rod performance.
With platforms that include Chevrolet, Ford, Mopar, GM trucks, LS and LT engines, and countless swap-specific applications, Hedman Hedders supports the full spectrum of American performance. Their products are trusted by racers, restorers, and custom builders for their combination of strength, precision fitment, and dyno-proven horsepower.
For generations, Hedman Hedders has delivered the kind of performance, reliability, and craftsmanship that serious builders depend on. Whether you’re cruising, racing, or refining a custom project, Hedman provides the exhaust solutions that let your engine breathe—and perform—at its absolute best.
