# Stainless Works 2020-21 Silverado HD 6.6L Redline Catback Black Tips

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