Improve sound and performance on your 2020–22 Shelby GT500 with a premium catback exhaust system from Stainless Works. Choose between our Legend or Redline Series for a drone-free aggressive exhaust note tuned specifically for the improved 5.2L Predator engine.
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 polished or black 5" slash-cut tips in a quad configuration, exiting at the factory location through the valance.
Built from corrosion-resistant 304 stainless steel and TIG welded in Streetsboro, Ohio — engineered for long-term durability and performance.
