Gibson 19-23 Silverado/GMC Sierra 1500 5.3L Crew Cab Cat-Back Dual Extreme Exhaust

If you're looking to give your 2019-2025 Chevrolet Silverado 1500 or GMC Sierra 1500 a more aggressive sound and a noticeable boost in performance, this Gibson cat-back exhaust system is a solid choice. Designed specifically for the 5.3L engine in Crew Cab models, it replaces your factory exhaust from the catalytic converter back, aiming to reduce backpressure and unlock more torque and horsepower. Many users report gains of around 18-20 horsepower with this setup.

This system features a baffled and chambered muffler, known as the Superflow™ CFT Muffler, which is designed to provide an aggressive, throaty sound without excessive interior drone, even under towing conditions. The tubing is made from stainless steel and is mandrel-bent to ensure smooth airflow. It includes polished stainless steel, slash-cut tips that exit straight out the back, measuring 4.0 inches in diameter. These tips are designed to work with most bumpers, roll pans, and trailer hitches. The entire system is a bolt-on installation, meaning no welding is required, and it utilizes factory-style hangers for a straightforward fit.

Included with the exhaust are all the necessary stainless band clamps and hardware for installation. Gibson backs this system with a Lifetime Limited Warranty, giving you confidence in its durability and longevity. This is a well-built system that aims to improve both the sound and performance of your truck.
