Product Details
Gibson is known for making exhaust systems that improve the performance of trucks and SUVs. This cat-back exhaust system is designed specifically for your 2021-2023 GMC Yukon or 2021-2022 Chevrolet Tahoe with the 5.3L engine. It's built to give you better acceleration, more power for climbing hills, and increased capability when towing or passing. You'll notice the difference in low-end torque and horsepower, especially between 1800 and 3000 RPM, where dyno tests show gains of 10-15 horsepower and 15-20 lb-ft of torque.
This system is constructed from stainless steel, including mandrel-bent tubing and a Superflow™ muffler. The muffler uses baffles and chambers for an aggressive sound outside the vehicle, but it's designed to minimize interior drone, keeping the cabin quieter. It features polished stainless steel slash-cut tips and exits behind the rear tire for a clean look. Because it's a bolt-on system, installation is straightforward with no welding required, and it uses factory-style hangers for a secure fit. Gibson backs this exhaust with a Lifetime Limited Warranty.
