Hooker Headers®, a leading header manufacturer, provides a line of Super Competition & Competition headers, mufflers, and cat-back exhaust systems. The company, which now is one of Holley Performance Products brands, was established by Garry Hooker in 1962. It is widely known for its racing heritage. Hooker Headers helped more racers reach the Winner's Circle than any other header company. In the 1990s the company developed the Aerochamber muffler, which still is the most advanced muffler on the market.
