Gibson 14-18 GMC Sierra 1500 Denali 5.3L 3.5in Cat-Back Single Exhaust - Stainless

Gibson is known for making well-built exhaust systems that improve your truck's performance. This particular cat-back system is designed for the 2014-2018 Chevrolet Silverado 1500 and GMC Sierra 1500 with the 5.3L engine. It exits behind the rear tire and is crafted from polished stainless steel for a clean look and long-lasting durability.

This system is built to give you a noticeable boost in acceleration, hill climbing, and towing power, especially in the low-end RPM range where it matters most for trucks. Dyno tests show gains of 18-21 horsepower and 20-22 lb-ft of torque, primarily between 1800 and 3000 RPM. Despite being a performance exhaust, Gibson has focused on minimizing interior drone, so you get an aggressive sound outside without an annoying hum inside the cab. The Superflow muffler design helps achieve this while still allowing for improved exhaust flow.

Installation is straightforward thanks to the bolt-on design, which uses factory-style hangers and includes all necessary hardware. No welding is required, making it a hassle-free upgrade. This system is backed by a Lifetime Limited Warranty, giving you peace of mind with your purchase.
