    More Horsepower And Torque. Improve the performance of your Mustang throughout the entire RPM range with a Stainless Works Long Tube Headers Performance Connect with an X-Pipe. This system will replace the factory manifolds, catalytic converters and H-Pipe to give your ride an awesome, bolt on upgrade. Stainless Works Headers and X-Pipe will greatly improve your Mustang'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 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.

    Application. This Stainless Works Long Tube Header Performance Connect and X-Pipe combo is specifically designed to fit the 2011 to 2014 GT Mustangs. Please choose Catted or Off-Road from the options above.

      Sounds Amazing!!!

      So for this buy we bought the Catless x pipe, and boy did my ears rings after this. If you're going for a raspy loud sound this is all you! Great buy!
