Get a Boost in Power and Performance. Give your 4.6L V8 Mustang a real kick-in-the-pants boost in the power department. This Kooks 3” Off-Road X-Pipe is designed to work with the Kooks Long Tube Header, deleting your Mustang’s stock cats and engineering a significant improvement in exhaust flow for huge power gains. And yeah, it sounds wicked.

More of That Big Mustang Sound. The Kooks X-Pipe, together with the Long Tube Header, really brings out the best in your Mustang’s voice. The engine’s once-strangled roar rings out, from the tubular headers, through the de-catted mid-pipe and out to your choice of cat-back exhaust.

Deletes Factory Cats. Kooks engineered its high-flow 3” Off-Road X-Pipe to provide a significant increase in exhaust flow through bigger, smoother tubing and by removing the restrictive, power-sapping catalytic converters. Therefore, this system is not CARB certified and is not legal for use in California or states with California emissions rules. It is intended only for off-road use and not on the public highway.

Hand-Made Stainless-Steel. Like all quality exhaust components made by Kooks, the 3” Off-Road X-Pipe is hand-made right here in the USA. High-quality smooth-bend construction ensures smooth gas flow.

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