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 with a single, polished stainless steel slash-cut tip, giving your truck a more aggressive look and sound.

This system is built to give you a noticeable boost in low-end torque and horsepower, especially between 1800 and 3000 RPM, which is great for towing, climbing hills, and passing. Dyno tests show gains of 18-21 horsepower and 20-22 lb-ft of torque. The Superflow muffler is baffled and chambered, meaning it's designed to flow well without needing internal packing, which helps keep interior drone to a minimum while still providing an aggressive sound outside the vehicle. All the tubing is mandrel-bent stainless steel for smooth flow and corrosion resistance, and it comes with factory-style hangers and all necessary hardware for a hassle-free, bolt-on installation that requires no welding.

This Gibson cat-back exhaust system is backed by a Lifetime Limited Warranty, so you can be confident in its durability. If you're looking to get more out of your Silverado or Sierra's 5.3L engine for work or play, this system is a solid option.
