Kooks 3 in. Off-Road X-Pipe (99-04 4.6L w/ Long Tube Headers)Find parts that fit my vehicle

Power and Performance. Engine performance is a function of torque and horsepower. The amount of torque is a measure of the quantity of work performed, and horsepower is a measure of how fast. By stabilizing the turbulent gas flow from the two individual exhaust banks, the Kooks 3 in. Off-Road X-Pipe boosts both horsepower and torque. You benefit from the ultimate driving experience.

Better Sound, More Power. Equalizing the exhaust flow from both sides of the engine has the fortunate consequence of not only boosting power, but also improving the noise that comes out of your exhaust system. The new sound is quieter, but higher pitched and more pleasing to the ear.

Neuter that Cat! The Kooks 3 in. Off-Road X-Pipe doesn't just neutralize the catalytic converter, it gets rid of it altogether. You get much better power, but you can't drive your Mustang on the street in this configuration. Some consider this a small price to pay for the privilege.

Construction and Finish. The Kooks 3 in. Off-Road X-Pipe is composed of aircraft-grade 304 stainless steel. This particular grade was chosen for its durability and resistance to corrosion. The natural stainless steel finish looks pretty, but offers no heat resistance.

Warranty. The Kooks 3 in. Off-Road X-Pipe is covered by a limited lifetime warranty against defects in materials and workmanship.

Application. The Kooks 3 in. Off-Road X-Pipe fits all 1999-2004 Mustang 4.6L models with long tube headers.
