Gibson 2017 GMC Sierra 1500 Base 5.3L 3in/2.25in Cat-Back Dual Extreme Exhaust - Stainless

If you're looking to give your 2014-2018 Chevrolet Silverado 1500 a more aggressive sound and a bolder look, this Gibson Dual Extreme Cat-Back exhaust system is a solid choice. Designed specifically for the 5.3L engine, this system replaces your factory exhaust from the catalytic converter back, exiting behind the rear tires at an aggressive angle for a powerful street presence. It's built to provide a mean performance sound that's noticeable without excessive interior drone, thanks to its Superflow™ CFT muffler which uses baffles and chambers instead of internal packing.

This system is constructed from durable stainless steel, including the mandrel-bent tubing and the polished slash-cut tips, ensuring it stands up to the elements. Gibson claims dyno-tuned performance gains of 15-20 horsepower with this setup. Installation is designed to be straightforward, as it's a bolt-on system that uses factory-style hangers and includes all the necessary hardware, meaning no welding is required. This makes it a more accessible upgrade for many truck owners.

The Dual Extreme system is Gibson's answer for those wanting a truly aggressive exhaust note and appearance. It comes with a Lifetime Limited Warranty, offering peace of mind for your investment. While it's designed for a powerful sound, Gibson has worked to minimize interior drone, so you can still enjoy a comfortable cabin experience on longer drives.
