Improve sound and performance on your 2015+ Shelby GT350 & GT350R with this Legend catback from Stainless Works. We?ve engineered a drone free aggressive muffler tuned specifically for this improved coyote engine from Ford. Featuring the latest in active exhaust technology, our in-house engineered valve bolts directly to the factory electronics to allow for all exhaust modes. From the closed valve ?Quiet? mode, to the chambered ?Normal? mode and to the wide open straight through design on the ?Track? mode. In addition to the tuned mufflers, we?ve also utilized 3? tubing into our X-pipe crossover for an improvement in flow over the stock exhaust. Our Legend series is designed to create our signature growl, increase volume over stock, yet maintain a comfortable cabin environment. We design Legend systems with the daily-driver in mind, improved tone with restrained loudness. A system that still gets the blood flowing, but allows for a comfortable ride. This system utilizes your OEM tips. Designed to fit to the performance connection point. Exits out at factory location through the valance. This system is built from corrosion resistant 304 stainless steel and TIG welded at our state of the art facility in Streetsboro, Ohio. As always we stand by our products with a lifetime warranty on material and craftsmanship.
