By nature of its design, it is legal for sale and use in all 50 states. Replacement parts included.

Upgrade the exhaust on your 2020-23 Chevy Silverado or GMC Sierra HD with this 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 an bolt-on install to the factory manifolds or connect without the Y to our Long Tube Headers for a True Dual system.

Out of the box this system fits the 6.6L gas motor in both 2 wheel and 4 wheel drive. It fits all cab/bed configurations but some will require minor trimming.

Built from corrosion resistant 304 stainless steel, our headers are TIG welded for strength and durability at our state-of-the-art facility in Streetsboro, Ohio. We stand by our products with a lifetime warranty on materials and craftsmanship, and as always, our products are proudly made in the USA.
