Description

With Hooker Super Competition the objective has always been to make the maximum horsepower and to put it at the optimum point in the power curve. It takes a lot of time and money to do the job right. We will sometimes spend up to 2 to 3 times more just to make the Super Competition header work only 5 to 10 percent better. That commitment to excellence has made Hooker Headers the winningest header manufacturer in automotice drag racing history.
