Description
Improve Horsepower And Torque. The Kooks Long Tube Header and Off-road Shorty X-pipe combo kit for the automatic 2005 to 2010 GT Mustangs will balance out the exhaust pressure to increase flow over the restrictive stock factory exhaust system resulting in more horsepower, torque, and better throttle response.

Quality Construction. Manufactured from 1-5/8" mandrel bent 304 stainless steel tubing Kooks Long Tube Headers are TIG welded for strength, and feature a leak-free ball flange design to fit perfectly into the included 2.5" diameter 304 stainless steel Shorty X-pipe for excellent exhaust flow and performance.

Recommended Upgrade. To realize the full power potential that this Header and X-pipe combo kit has to offer, AmericanMuscle recommends a custom tune with a Mustang Handheld Tuner to reprogram the vehicles computer (ECU) for proper operation.

Application. This Kooks Header and matching Off-road X-pipe combo kit is designed specifically for the 2005 to 2010 4.6L GT Mustangs equipped with an automatic transmission.

Technical Note: This Kooks product is intended for off road use, and is not legal for use in emission restrictive states.

    Extremely Pleased With Purchase!

    I just had my Kooks Headers put in and I have to say that this should of been one of the first Mods. My 2010 GT sounds like a muscle machine coming down the street. My Torque went up about about 21+ but my HP stayed the same. I was a little confused on why my HP was the same. But When I got home and loaded the BAMA TUNE I know for fact I gained some more HP and even more TQ right away. I want to re dyno it with the BAMA. Go with BAMA people! Thanks again AM.COM for providing the best service!
