For maximum performance gains on your new Mustang GT500, JBA has a complete stainless steel long tube header system that delivers more power and torque than any other header system. These headers have a 1 3/4 inch tube and a 3 inch collector. These new headers take full advantage of the redesigned chassis and new engine. You must run the JBA 3 inch x pipe with this kit. We also recommend the 3 inch stainless steel cat back from JBA.
