Gibson 20-21 GMC Sierra 2500HD/3500HD 6.6L Cat-Back Single Exhaust System Stainless - Black Elite

If you're looking to give your 2021-2025 Chevrolet Silverado 2500 HD or GMC Sierra 2500 HD a more aggressive sound and a custom look, this Gibson Black Elite cat-back exhaust system is a solid choice. It's designed to replace your factory exhaust from the catalytic converter back, improving exhaust flow and giving your truck a deeper, more satisfying tone without excessive interior noise.

Gibson builds this system using high-quality T-304 stainless steel tubing that's mandrel-bent to ensure consistent diameter and smooth airflow. The heart of the system is Gibson's Superflow CFT muffler, which uses baffles and chambers instead of internal packing to create a deep, mild exhaust note with minimal interior drone. The system is finished off with stylish, rolled slash-cut tips that feature a durable black ceramic coating, exclusive to Gibson's Black Elite line. Everything you need for installation, including hardware and factory-style hangers, is included, making it a straightforward bolt-on upgrade.

This cat-back system is made in the USA and comes with a limited lifetime warranty from Gibson, reflecting their commitment to quality and performance. You'll notice an improved exhaust note and a distinct visual upgrade with the black tips.
