Gibson is known for making well-built exhaust systems that improve the performance of trucks and SUVs. This cat-back exhaust system is designed for your 2021-2025 Chevrolet Silverado 2500 HD or GMC Sierra 2500 HD, and it's built to give you more power when you need it most. Whether you're hauling heavy loads, climbing steep grades, or just need a little extra boost for passing, this system aims to deliver improved acceleration and towing capability.

This system features a baffled and chambered muffler with no internal packing, which helps reduce interior drone while still giving you an aggressive sound outside the truck.

It exits behind the rear tire with polished stainless steel, slash-cut tips for a clean look. Installation is straightforward thanks to the bolt-on design, which uses factory-style hangers and includes all the necessary hardware, meaning no welding is required.
