Gibson 21-22 GMC Yukon XL 1500/ Suburban 1500 5.3L 2/4wd Cat-Back Dual Sport Exhaust

Starting with polished stainless steel slash-cut tips exiting behind the rear tire, this Gibson Dual Sport Cat-Back exhaust system is built to give your 2021-2025 Chevrolet Suburban a distinct look and sound. The system uses a baffled/chambered muffler with no internal packing, which Gibson calls their Superflow™ muffler, designed to produce a powerful, deep exhaust tone without creating annoying interior drone. This means you get an aggressive sound outside the vehicle while keeping the cabin comfortable for everyday driving or towing.

The entire system is constructed from stainless steel, including the mandrel-bent tubing, which helps ensure consistent exhaust flow and resists corrosion for a long service life. Installation is designed to be a hassle-free, bolt-on process with no welding required, making it a straightforward upgrade for many DIYers. Dyno testing shows this system can add an average of 10-15 horsepower and 15-20 lb-ft of torque, providing a noticeable improvement in performance to complement the new sound and appearance.

This cat-back system replaces the factory exhaust from the catalytic converter back, exiting behind the rear wheel on each side. It's a solid option if you're looking to enhance the style and performance of your Suburban while maintaining a comfortable interior environment, even when towing.
