    Description

    Improve Horsepower And Torque. The Kooks Long Tube Header and Catted Shorty X-pipe combo kit for the Shelby GT500 Mustang 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 1-3/4" 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 3" diameter 304 stainless steel Shorty X-pipe for excellent exhaust flow and performance.

    Natural Finish. These Kooks Headers feature a natural stainless steel finish, which provides an aggressive appearance to your engine bay. This is not a heat-resistant coating, AmericanMuscle recommends the use of Exhaust Heat Wrap for high performance applications.

    Recommended Upgrade. To realize the full power potential that this Kooks Long Tube Header and X-pipe Kit has to offer, AmericanMuscle recommends a custom tune with either a SCT SF3 or SCT iTSX Wireless Custom Tuner.

    Application.
    This Kooks Long Tube Header and matching catted shorty X-pipe combo kit is designed specifically for the 2011 to 2014 Shelby GT500 Mustangs.
