Hedman's Standard-duty, Uncoated Hedders are manufactured using 18 gauge, mandrel bent primary tubes (some models built using thicker 16 or 14 gauge tubing), and 1/4 flanges (some models use 3/8" flanges). The factory black paint applied to uncoated hedders is not hi-temp, and is for pre-installation protection only. For the ultimate in protection against the elements, we suggest Hedman's Original HTC coating.
Hedman has two different designs of the standard-duty headers. There is the Standard-Duty and the Tork-Step.
The Tork-Step hedders offer the following advantages:

Improves Combustion Effeciency

Adds Torque Throughout Entire Torque Range

Increases Horsepower Output

Quicker Acceleration Times

Improved Fuel Effeciency

State of the Art in Header Design

Race Exhaust Technology for the Street

A Must Have for any Towing or Wide Open Throttle Applications
