Kooks 1-5/8-Inch Long Tube Headers with Catted X-Pipe (05-10 Mustang GT)Find parts that fit my vehicle

Improved Torque and Horsepower at the Rear Wheels. The Kooks 1-5/8” Headers and Catted X-Pipe Combo removes traditional restrictive factory cats and replaces them with high-flowing race cats and big-bore tubing to help your Mustang breathe better, which produces instant power gains and provides a basis for future power tuning. The header inlet ports are hand ground by experts at Kooks to guarantee a perfect fit.

Big Throaty Sound. Big-bore piping in the Kooks Headers coupled with race cats in the X-Pipe work with the engine’s firing pulses to harness extra power. They generate a raspy, racy exhaust sound that builds to a jaw-dropping rumble.

High-Power Race Cats. The Catted X-Pipe features super-flow race cats specially designed to minimize restrictions. They don’t choke your Mustang’s breathing like factory cats.

Handcrafted Aircraft-Grade Stainless-Steel. Kooks Long Pipe Headers are handcrafted from tough T304 stainless steel. Smooth-radius mandrel-bent curves and hand-ground inlet ports get rid of any obstructions to maximize exhaust flow.

Tune Recommended. The Kooks Headers and Catted X-Pipe help your engine breathe much more freely. Tuning of the ECU is recommended to maximize the power gains.
