Product Details
Gibson is known for making well-built exhaust systems that offer a noticeable improvement in sound and performance. This Dual Sport Cat-Back system is specifically made for your 2014-2018 Chevrolet Silverado 1500 with the 5.3L engine, giving it a more aggressive look and sound that exits behind the rear tire. It’s designed to set your truck apart whether you're on the street or heading off-road.
This system uses 3-inch diameter tubing that steps down to 2.25 inches for the tips, all made from polished stainless steel to resist corrosion. The Superflow muffler is baffled and chambered, engineered to produce a powerful, deep exhaust tone without the annoying drone inside the cab. Installation is straightforward with a bolt-on design that requires no welding, using factory-style hangers and including all the necessary hardware. Dyno testing shows this system can increase horsepower by 18-20 and torque by 15-20 lb-ft, giving your truck a bit more get-up-and-go.
You'll also get a Lifetime Limited Warranty from Gibson, backing the quality of this stainless steel exhaust. The slash-cut, clamp-on tips add a clean, finished look to the rear of your truck.
