Previously used exclusively in the aerospace industry, Hedman Hedders recognized it's potential for improving both the lifespan, and functionality of exhaust headers.
Hedman's Standard-duty, Uncoated Headers are manufactured using 18 gauge, mandrel bent primary tubes (some models built using thicker 16 or 14 gauge tubing), and 0.25 flanges (some models use 0.375" flanges).
The factory black paint applied to uncoated headers is not hi-temp, and is for pre-installation protection only. For the ultimate in protection against the elements, Hedman Hedders suggest Hedman's Original HTC coating.
All Hedman street Hedders are MADE IN THE USA, and are backed by a lifetime warranty against manufacturing defects!
