Overview

Improve sound and performance on your 2015–20 Shelby GT350 or GT350R with a premium Legend/Redline catback exhaust from Stainless Works. We've engineered a drone-free aggressive muffler tuned specifically for the 5.2L Voodoo engine from Ford.

Featuring the latest in active exhaust technology, our in-house engineered valve bolts directly to the factory electronics to retain all exhaust modes. From the closed valve "Quiet" mode, to the chambered "Normal" mode, and the wide open straight-through design on "Track" mode — you get full control of your sound.

This system utilizes 3" mandrel-bent tubing with your choice of H-pipe or X-pipe crossover for improved flow over the stock exhaust. Available with Factory Connect or Performance Connect options and designed to work with your OEM tips.

Built from corrosion-resistant 304 stainless steel and TIG welded in Streetsboro, Ohio — engineered for long-term durability and performance.
