    Description

    More Horsepower And Torque. Improve the performance of your high powered Shelby GT500 throughout the entire RPM range with a Stainless Works Long Tube Header and Catted Shorty X-Pipe combo kit from AmericanMuscle. This Stainless Works Header and X-Pipe kit will greatly improve your Shelby's exhaust flow over the restrictive stock manifolds and Mid Pipe to significantly increase your Pony's horsepower and torque.

    Superior Construction. Manufactured in the USA from 1-7/8" mandrel bent 304 stainless steel tubing for superior airflow, Stainless Works Long Tube Exhaust Headers are TIG welded and feature a one piece 3/8" thick header flange for added strength and optimal leak-free performance.

    Race Car Growl. The included Stainless Works 3" diameter 304 stainless steel high-flow catted X-Pipe not only improves exhaust flow to increase power, but it also adds a crisp raspy, race car growl to the sound of your Mustangs exhaust with its modern merged "X" crossover design.

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

    Application. This Stainless Works Long Tube Header and Catted X-Pipe combo kit is specifically designed to fit the 2011 to 2014 Shelby GT500 Mustangs equipped with the supercharged DOHC 32-valve V8 engine.
