    Get a Boost in Performance and Power. Give your Mustang GT a big boost in power and torque. This Kooks 3” Off-Road X-Pipe is engineered to work as a team with the Kooks Long Tube Header, removing the Mustang stock cats and generating a huge gain in exhaust flow for big power improvements. It also sounds fantastic.

    More of That Mustang Sound. The Kooks X-Pipe, in conjunction with the Kooks Long Tube Header, really lets the best of your Mustang’s voice out. The once-strangled sound truly roars, from the long pipe headers, through the de-cat mid-pipe and on out to your chosen aftermarket exhaust.

    Deletes OEM Cats. Kooks engineered its 3” Off-Road X-Pipe to help provide a major increase in gas exhaust flow through smoother, bigger diameter tubing and the removal of the power-sapping, restricting catalytic converters. As a result, this exhaust system is neither CARB certified nor legal for use in California or any state that uses California emissions regulations. It is intended to be used only off-road and not on the public highway.

    Hand-Crafted in Stainless-Steel. Like all of the Kooks quality exhaust components, this 3” Off-Road X-Pipe is hand-made here in America. The high-quality construction with smooth bends ensures gases flow fast and unimpeded.

    Application. The 3” Off-Road X-Pipe works with the Kooks Long Tube Headers on 2005 through 2010 Mustang GTs.

    2 Top Rated Questions

    Why do these only fit kooks long tube headers? Why not any long tube headers.

    • The Kooks 3 in. Off-Road X-Pipe is designed to meet up with the Kooks Long Tubes. With long tubes, the exit from the header will be unique for each brand, and they will not match up brand to brand.

    I have a 2010 V6, would I still be able to use the pypes true dual conversion kit and cut some pipe to make this all fit?

    • This Kooks 3 in. Off-Road X-Pipe is specifically designed for use on 05-10 GT Mustangs with long tube headers and will not fit properly on a V6 model Mustang.
