These Hooker Super Competition Headers are a tuned length long tube header. All emission control devices come with this header. They are built with 18 gauge 1-3/4″ primary tubes that improve the engines ability to breathe better then the stock manifolds. Tuned length primaries and long transition 3″ collectors increase exhaust velocity for a great performance increase. Long tube headers are good for maximum torque and power.
