Stainless Works 2015+ Ford Shelby GT350 Legend Factory Connect X-Pipe Catback Exhaust w/Valves

The 3-inch diameter tubing in this Stainless Works Legend cat-back system is a key detail, especially when paired with the X-pipe crossover. This setup is designed to improve exhaust flow over the stock system on your 2015-2020 Shelby GT350 and GT350R. The goal here is to give that Coyote engine a more aggressive growl and better performance, while still keeping things comfortable for daily driving. Stainless Works has tuned these mufflers specifically to avoid that annoying drone you can get on longer trips, so you can enjoy the improved tone without the cabin noise.

What really sets this system apart is its active exhaust technology. The integrated valves bolt right up to your car's factory electronics, meaning you can switch between different sound modes. You get a quiet mode for when you need to be discreet, a normal mode with a chambered muffler design, and a wide-open track mode that lets the engine breathe freely. This system is built from corrosion-resistant 304 stainless steel and TIG welded at their facility in Ohio, so it's made to last. It connects directly to your factory exhaust points and exits at the stock location, using your OEM tips.

This Legend series exhaust is a solid option if you're looking for a signature Stainless Works growl that increases volume over stock but maintains a comfortable cabin environment. It's designed to get the blood flowing with its improved tone, but it’s still restrained enough for a comfortable ride. Stainless Works backs this system with a lifetime warranty on materials and craftsmanship.
