      Description

      Performance Exhaust Upgrade. The Kooks 1-7/8-Inch Long Tube Headers with Catted X-Pipe are designed to enhance exhaust flow, increasing horsepower and torque for your Mustang GT. This kit replaces the factory exhaust manifold and catalytic converter assembly to optimize exhaust scavenging and improve engine efficiency, ideal for enthusiasts seeking a performance boost while maintaining emissions compliance.

      Construction and Appearance. Crafted from premium 304 stainless steel, these long tube headers and X-pipe offer exceptional durability and corrosion resistance. The headers feature mandrel-bent 3-inch diameter tubes, ensuring smooth exhaust flow and a professional polished finish that comes uncoated for a clean metallic appearance.

      Installation. Installation requires moderate automotive experience and standard hand tools; no drilling is necessary since the headers bolt directly to existing mounting points. Proper fitment allows a straightforward swap with OEM components for a clean and reliable installation.

      Warranty. This product includes a limited warranty as specified by the manufacturer.

      Application. Specifically engineered to fit 2011 through 2014 Mustang GT models equipped with the 5.0L 4V engine, ensuring compatibility and maximum performance gains for these model years.
