About Hooker

The Hooker philosophy is simple - make real, useable power by balancing the intake and exhaust pressure waves. This efficiently expelles all the burnt gases while drawing in the maximum fresh charge of fuel and air. The Hooker team will sometimes spend twice as much time developing a header to find better performance. Hooker Headers - Do It Right The 1st Time.
