S/S Headers - 01-06 GM P/U- Suburban V8

The HEDMAN Stainless Steel Headers for 01-06 GM P/U Suburban V8 (Part 62700) deliver a direct bolt-on performance upgrade designed specifically for big block Chevy applications in full-size trucks and SUVs. These street-legal headers replace restrictive factory exhaust manifolds with mandrel-bent primary tubes and a stock collector flange, improving exhaust scavenging and horsepower while maintaining everyday driveability. Supplied as a complete pair with gaskets and hardware included, installation is straightforward for owners seeking measurable performance gains without extensive fabrication.

The 1.75-inch primary tube diameter is engineered for big block displacement, optimizing exhaust velocity across the RPM range typical of heavy-duty pickup and SUV duty. Stainless steel construction resists corrosion from road salt and moisture exposure—critical for vehicles operated in harsh climates or coastal environments. The stock collector flange maintains compatibility with original or aftermarket exhaust systems downstream, eliminating fitment guesswork. Weighing 23.1 pounds per pair and measuring 16.5 x 8.75 x 30 inches, these headers clear stock engine bays without modification while providing the thermal and acoustic characteristics buyers expect from purpose-built performance headers.

Buyers upgrading 2001-2006 GM full-size trucks and Suburbans typically seek better throttle response, improved fuel efficiency under cruise conditions, and the reliability of a known brand. HEDMAN's street headers are engineered as a foundation for users planning additional intake or fuel system upgrades, or simply looking to reclaim power lost to factory restrictions. The natural stainless finish develops a subtle patina over time while resisting rust, and the included gasket set ensures a leak-free seal at the cylinder head. This is a direct performance upgrade for owners committed to sustained improvement rather than a quick bolt-on novelty.
