    Do It Once, Do It Right

    Hedman Elite Headers are the best you can buy. They have thicker flanges, stronger tubing, and thermal coating to withstand full-throttle thrashing and torturous towing. Their extreme-duty construction protects against burnout and exhaust leaks caused by the excessive heat and vibration of high-performance applications. Elite Headers outlast and outperform ordinary headers. All Hedman street headers are made in the USA with a 5-year coating warranty and lifetime product defect warranty.

    Note: Installing coated headers on an engine during the break-in period will cause discoloration. It is recommended that the factory manifolds or an old set of headers are used while breaking in an engine.

    Features
    • Hefty 3/8" flanges
    • Shorty or full-length design
    • Thick wall 14-gauge primary tubes
    • Built to withstand tough applications
    • HTC thermal coating with 5-year warranty
    • Lifetime warranty against manufacturing defects
