    These standard-duty Hedman HTC Coated Headers come from the factory with an extremely durable, protective ceramic-metallic coating. Hedman Hedders pioneered the automotive application of ceramic-metallic coatings in the early 1980s. Previously exclusive to the aerospace industry, Hedman Hedders recognized the coating's potential to improve both the lifespan and functionality of exhaust headers. All Hedman street headers are MADE IN THE USA and backed by a lifetime warranty against manufacturing defects! The HTC coating is covered for a full five years.

    NOTE: Installing coated headers on an engine during the break-in period will cause discoloration. The use of factory manifolds or an old set of headers is recommended while breaking in an engine.

    Features
  • Coating offers protection up to 1400°
  • Won't chip, peel, or "blue" like chrome
  • Superior heat insulation
  • Increased exhaust velocity for more power
  • Made in USA

    JEGS Easy Kits are designed by JEGS Professionals to help you get all the performance parts you need.
