Description
Elevate the sound and performance of your 2015-2020 Ford Shelby GT350 or GT350R with the Stainless Works Legend Performance Connect X-Pipe Catback Exhaust with Valves. Designed to enhance the natural characteristics of the 5.2L Voodoo engine, this system offers a refined balance between aggressive tone and daily-driving comfort, all while integrating flawlessly with the factory active valve functionality.
This high-performance system features full 3-inch mandrel-bent tubing, ensuring superior exhaust flow and reduced back pressure. The X-pipe crossover enhances mid- to high-RPM performance, delivering a crisp, refined tone that defines the Legend sound signature. Developed for enthusiasts who want a deep, growling exhaust note without overwhelming cabin noise, the Legend series strikes a perfect balance between livability and performance sound.

This Performance Connect version is designed for use with Stainless Works long tube headers, allowing for a full unrestricted 3-inch exhaust path and maximum horsepower gains. It exits cleanly through the rear valance using the OEM tips for a seamless, factory-fit look.
Built in the USA from corrosion-resistant 304 stainless steel and precision TIG welded for strength and reliability, this exhaust system delivers exceptional durability and long-term performance.
