Hedman Street Hedders are one of the best buys in bolt-on performance.

For the price, no other part can give you the horsepower and fuel-economy improvements of Hedman headers. They make Hedman Street Hedders so well that they guarantee them to be free from defects--including cracks in the tubes and welds--for the life of the headers. Hedman Street Hedders are available in black painted or ceramic coated finishes, and, as an added bonus, they also come with all necessary gaskets and mounting hardware.

Warranty

Hedman Hedders warrants their Street Headers against defects in materials and workmanship for the lifetime of the product. This includes tube cracks, bad welds, warped flanges, etc. In addition, the HTC ceramic coating utilized on Hedman's ceramic-coated headers is warranted for 5 years from the date of purchase against chipping, peeling, fading, discoloring, and rusting. Headers subjected to improper installation, off-road use, road hazards, and the use of Thermal Wrap are void of any warranty whatsoever. The ceramic-coated headers' finish warranty is void if the headers are used on engines equipped with superchargers, turbochargers, or nitrous systems. Breaking in a new or rebuilt engine with HTC coated Hedders will void coating warranties. Hedman recommends the use of cast iron exhaust manifolds or old Hedders during the initial break-in period of approximately 20 minutes. This will avoid damage to the coating's high-luster finish. You must have at least one hour of normal engine use before you can run your engine or vehicle on a dyno. The use of NOS, superchargers, or turbochargers will void the HTC warranty.
