Kooks 05-10 Ford Mustang GT Shelby GT Bullitt 1-5/8 x 2-1/2 (3V) Header & Catted H-Pipe Kit

Built from T304 aircraft-quality stainless steel, this Kooks header and catted H-pipe kit is designed for the 2005-2010 Ford Mustang GT with the 4.6L 3V engine. The 1-5/8 inch primary tubes are mandrel bent to maintain consistent diameter, which helps improve exhaust gas flow out of the engine. This is a crucial step in getting more power from your Mustang, especially if you're looking to make significant upgrades to the engine's breathing. The kit includes long tube headers and a 2-1/2 inch catted H-pipe that connects to your stock exhaust system.

The headers feature 3/8 inch thick laser-cut flanges that ensure a solid seal against the cylinder heads, and they use the stock bolt pattern for a straightforward installation. Kooks also includes their high-flow, 400-cell catalytic converters, designed to offer a performance boost while still meeting emissions standards for non-forced induction applications. All the necessary hardware for installation is included, making this a complete package to upgrade your Mustang's exhaust system. Kooks has been crafting performance exhaust for over 50 years, and all their products are handcrafted in the USA.
