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

Gibson Performance is known for making well-built exhaust systems that balance performance and style. This Black Elite Series cat-back exhaust is a prime example, designed specifically for your 2014-2018 Chevrolet Silverado 1500 or GMC Sierra 1500 with the 5.3L engine. It's built to give your truck a more vigorous, deep exhaust note while also looking sharp.

The system features a Superflow CFT Stainless Performance Muffler that uses baffles and chambers instead of internal packing, which helps create that aggressive sound without adding much interior drone. The 3.5-inch, rolled slash-cut tips are made from T-304 stainless steel and finished in a durable black ceramic coating, a process exclusive to Gibson's Black Elite line. The tubing itself is also mandrel-bent stainless steel, ensuring consistent flow and corrosion resistance. Gibson claims an estimated 10-15 horsepower and 15-20 lb-ft of torque improvement with this system.

Installation is designed to be straightforward with a bolt-on process that uses factory-style hangers and includes all the necessary hardware. This system is backed by a limited lifetime warranty from Gibson, reflecting their commitment to quality and durability.
