Gibson 11-19 GMC Sierra 2500 HD Denali 6.0L 3.5in Cat-Back Single Exhaust - Stainless

You're getting a complete Gibson cat-back exhaust system for your 2011-2019 Chevrolet Silverado 2500 HD or GMC Sierra 2500 HD. This kit includes all the necessary hardware and factory-style hangers, making it a straightforward bolt-on installation with no welding required. The system features a single, polished stainless steel slash-cut tip that exits behind the rear tire, giving your truck a clean, professional look.

This Gibson exhaust is built with mandrel-bent stainless steel tubing and a Superflow™ baffled/chambered muffler. It's designed to increase low-end torque and horsepower, especially between 1800 and 3000 RPM, which is great for towing, hill climbing, and passing. You can expect an average gain of 10-15 horsepower and 15-20 lb-ft of torque. Despite its performance enhancements, Gibson has worked to minimize interior drone, offering an aggressive sound outside the cab while keeping it more comfortable inside.

This system is constructed from polished stainless steel for durability and appearance, and it's backed by a Lifetime Limited Warranty from Gibson. If you're looking to get more out of your truck's engine for work or play, this cat-back system is a solid option.
