Through the years, Hedman Hedders have not lost it's magic touch. No matter what model of car you have, adding Hedman Headers to it produces increased power and torque. In the old days of performance exhaust making, engineers weld up pipes until they find the right concoction for more power and torque. Hedman Hedders have mastered the technique even without the aid of computer dynos and mandrel-bending machines. Today, Hedman Headers are designed using the latest CAD technology. Mandrel-bent pipes are standard for their improved gas flow and sleek looks.Headman Headers have free-flowing, multi-tube system allowing exhaust pulses to free-travel to the exhaust collector. On a stock exhaust manifold, the exhaust pulses build up a pressure inside the manifold. With Hedman Hedders, back pressure is reduced as each exhaust port gets its own tube. This lets the engine focus on sending horsepower to the rear wheels, not on pushing exhaust gases out the tailpipe.There is a Hedman Hedder available for every car. Sport compacts, imports, trucks, or muscle cars from the States are readily available in stores. For the budget-conscious, there's the black-painted Hedman Headers. And for that hardcore hot-rodder cashing in for durability, there's the ever-popular HTC coating for long life and great looks.For every Hedman Hedders installed in your car, you will feel the kind of power that's way different from the others---just like in the old days.
