 Hedman believes that a good set of headers should be made to last, as well as add performance. That's why each Hedman Hedder is made by hand, in America. Hedman Hedders were originally designed for racing but they give tremendous boosts of power and performance to street vehicles as well. Since headers naturally increase the efficiency of a vehicle's engine, you will experience improved power for passing, hauling loads, towing, etc. by simply bolting a pair on in place of your exhaust manifold. Hedman Hedders are designed specifically for each application and are, dollar for dollar, your best performance investment.
