Hedman Painted Hedders

HEDMAN – PAINTED HEDDERS

Is that power-robbing stock manifold still on your vehicle? If you answered yes, then replace it with a Hedman Painted Header to lower your operating temps and release extra horsepower and torque from your engine. These hedders are designed for painting, so order a can of header paint in the color that best suits your vehicle. Hedman Hedders have always been made in the USA since the company was founded over 50 years ago. Bob Hedman started out making hedders as a one man shop but word spread fast about the horsepower and torque that Hedman hedders were producing. His hedders have been in demand by top engine builders and racers since the start. Hedman’s time perfecting hedders on the track and on the dyno ensures you will get optimum performance with every Hedman Header whether it is installed on your race car or daily driver.
