Gibson 21-22 GMC Yukon XL 1500/Chevrolet Suburban 1500 5.3L Cat-Back Single Exhaust - Stainless

Gibson is known for making well-built exhaust systems that improve your vehicle's performance. This cat-back exhaust system is specifically designed for your 2021-2025 Chevrolet Suburban with the 5.3L engine, aiming to give you a noticeable boost in power where you need it most. It exits behind the rear tire, offering a cleaner look and a sound that's more aggressive outside the vehicle while staying quieter inside.

This system uses mandrel-bent stainless steel tubing for smooth exhaust flow, which helps the Superflow™ muffler do its job efficiently. Dyno tests show this setup can add about 10-15 horsepower and 15-20 lb-ft of torque, particularly at lower RPMs, making a difference for hill climbing, towing, and passing. The muffler itself is baffled and chambered, designed to provide that improved performance without the excessive interior drone that can be common with other performance exhaust systems. You also get a polished stainless steel slash-cut tip that clamps on, giving a professional finish.

Installation is designed to be straightforward, with all the necessary hardware and factory-style hangers included, meaning no welding is required. This bolt-on system is backed by Gibson's Lifetime Limited Warranty, giving you peace of mind with your purchase.
