Hedman Headers - Pontiac 326-455,1964-81 Grand Prix, Le Mans, GTO, Firebird Set

HEDMAN Standard Uncoated Headers; 1-5/8-2" Tube Diameter; 3" Coll.; FULL LENGTH Design

LONG-TUBE design provides ample exhaust flow to let your 326-455 Pontiac engine breathe easy, and produce maximum horsepower and torque. These headers are uncoated, and ship from the factory with a temporary black paint that will burn off when submitted to normal operating temperatures. They are also available with a ceramic-metallic finish.
