Upgrade the exhaust on your 2020–23 Chevy Silverado or GMC Sierra HD 2500/3500 with a premium Legend or Redline catback exhaust from Stainless Works.
The Legend system is designed 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.
We designed this Redline system to maximize the volume and tone of the engine, while still eliminating any drone in the cabin. Resulting in a feeling that will make you want to high-five your friends in the face.
This 3" exhaust features dual chambered mufflers with 4" matte black or polished slash-cut tips. Use the included Y-pipe for a bolt-on install to the factory manifolds or connect without the Y to our Long Tube Headers for a true dual system.
Built from corrosion-resistant 304 stainless steel and TIG welded at our state-of-the-art facility in Streetsboro, Ohio — engineered for long-term durability and performance.
