Upgrade the exhaust on your 2020-21 Chevy Silverado or GMC Sierra HD with this catback exhaust from Stainless Works.

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" 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. 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.
