Optimize Your Shelby GT500's Performance with Stainless Works Headers and H-Pipe

Are you ready to take your 2011-2014 Shelby GT500 Mustang to the next level of performance? The Stainless Works 1-7/8-Inch Long Tube Headers with High Flow Catted H-Pipe combo kit is designed to dramatically enhance your Pony's power and torque throughout the entire RPM range. This advanced exhaust system replaces the restrictive factory manifolds and Mid Pipe, ensuring a significant increase in horsepower and torque for a more responsive and powerful driving experience.

Superior Quality and Design

Crafted in the USA, this Stainless Works kit boasts a high-quality construction using 1-7/8" mandrel-bent 304 stainless steel tubing. This premium material ensures superior airflow and durability, while the TIG welding guarantees a strong and leak-free connection. The one-piece 3/8" thick header flange adds an extra layer of strength for optimal performance. Additionally, the included high-flow catted H-Pipe, featuring a 3" diameter 304 stainless steel design, not only improves exhaust flow but also adds a classic muscle car rumble to the sound of your Mustang's exhaust.

Boost Your Mustang's Performance and Enjoyment

This Stainless Works combo kit is perfect for off-road and track use, delivering an unparalleled performance boost. With its long tube header design, free-flowing 1-7/8" mandrel-bent tubing, and matching high-flow catted H-Pipe, your Shelby GT500 will experience increased power and a deeper, more aggressive sound. Whether you're a daily driver or a weekend track enthusiast, this kit is tailored to enhance your Mustang's driving experience. Designed and manufactured in the USA, this kit is a must-have for any Shelby GT500 owner looking to unleash the true potential of their vehicle.
