Upgrade the exhaust on your 2020-21 Chevy Silverado or GMC Sierra HD with this catback exhaust from Stainless Works. We designed this Legend system 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 3" exhaust features dual chambered mufflers with 4" matte black 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. 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.
