These standard-duty Hedman Black Maxx Ceramic-Metallic Coated Headers come from the factory with an extremely durable, protective black ceramic-metallic coating, and can withstand temperatures up to 1400 degree F. Each set uses mild steel, smooth flowing, CNC mandrel bent tubes, that are hand-welded to ensure each pair is identical to the next. Hedman's unique, gasketless ball and socket collector design allows your vehicle's exhaust system to bolt up, even if it is not perfectly aligned with the header collectors. Each set includes a pair of gaskets, header flange bolts and collector bolts. No collector gasket is needed.

Features:

  • The coating offers protection up to 1400°
  • Won't chip, peel, or "blue" like chrome
  • Superior heat insulation
  • Increased exhaust velocity for more power

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.
