The standard-duty Hedman Hedders in this section come from the factory with an extremely durable, protective ceramic-metallic coating. Hedman Hedders, pioneered the use of ceramic-metallic coatings, back in the early 80's. Previously used exclusively in the aerospace industry, Hedman Hedders recognized it's potential for improving both the lifespan, and functionality of exhaust headers.

All Hedman street Hedders are MADE IN THE USA, and are backed by a lifetime warranty against manufacturing defects! Our HTC coating is covered for a full 5 years.

UNLESS SPECIFICALLY STATED, ALL HEADERS ARE DESIGNED FOR USE WITH FACTORY PROFILE CYLINDER HEADS! If your engine does not have factory cylinder heads, we strongly recommend you contact the aftermarket head manufacturer to confirm that the deck angle, exhaust port height and spark plug angle/position match the factory head design, before ordering your headers. If you are still unsure, please contact the Hedman Tech lines M-F 8am-4:30PM (Pacific) @ (562) 921-0404.

IMPORTANT!: Installing coated headers on an engine during the break-in period will cause discoloration. We recommend the use of factory manifolds, or an old set of headers, during the engine break-in period.
