1959-1964 Chevrolet Impala Long Tube Headers Hooker Super Competition 2171-1HKR actuator-vacuum-lines 2007-2008 Chevrolet Avalanche 364 CIDOverview 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% better. That commitment to excellence has made Hooker Headers the winningest header manufacturer in automotive drag racing history.
