Kooks 1-3/4" x 3" GT500 header and GREEN catted X-pipe kit — the bundled top-end for pulley-and-tune GT500 builds. GREEN catted X-pipe survives supercharged heat. The 1-3/4" primary is the right starting point for boosted GT500 builds.
Fits 2007-2010 Ford Shelby GT500 5.4L 4V. EGR fitting included on the headers. Connects directly to OEM cat-back at the X-pipe rear flange.
Kooks Headers & Exhaust has been hand-building stainless headers and exhaust systems in Statesville, North Carolina since 1962. Every component is welded by experienced fabricators in the same shop where the company's racing roots were established. 304 stainless construction handles supercharged heat and corrosion.
Includes 1-3/4" x 3" GT500 long tube headers, 3" x 2-1/2" GREEN catted X-pipe, and all required hardware. Pair with the OEM cat-back downstream.
