    Description

    Improve Horsepower And Torque. The Kooks Long Tube Header and Catted Shorty X-pipe combo kit for the manual 2005 to 2010 GT Mustangs will balance out the exhaust pressure to increase flow over the restrictive 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 catted X-pipe combo kit is designed specifically for the 2005 to 2010 4.6L GT and Bullitt Mustangs equipped with a manual transmission. Includes gaskets and 02 extensions.
