Gibson 15-18 GMC Yukon XL SLE 5.3L 2.25in Cat-Back Single Exhaust - Stainless

Gibson has been making exhaust systems for trucks and SUVs for a long time, and they're known for building well-made, performance-oriented parts. This Gibson cat-back exhaust system is designed for your 2015-2020 Chevrolet Suburban with the 5.3L engine, giving you a solid improvement in how your vehicle performs, especially when you need it most.

This system is built from polished stainless steel with mandrel-bent tubing, which means the pipes maintain their diameter throughout for better exhaust flow. It exits behind the rear tire with a polished, slash-cut tip. The Superflow™ muffler uses baffles and chambers instead of internal packing, which helps it flow better while keeping the sound inside the cab more comfortable, minimizing drone. Dyno tests show this system makes its best gains in torque and horsepower between 1800 and 3000 RPM, which is exactly where you want that extra boost for towing or climbing hills. You can expect an average increase of 18-21 horsepower and 20-22 lb-ft of torque.

Installation is designed to be a hassle-free, bolt-on process with factory-style hangers, meaning no welding is required. It comes with all the necessary hardware to get it installed and looking professional. Gibson backs this exhaust system with a lifetime limited warranty, giving you peace of mind.
