Gibson 15-19 GMC Sierra 2500 HD Base 6.0L 3.5in/3in Cat-Back Dual Split Exhaust - Stainless

If you're looking to give your 2011-2019 Chevrolet Silverado 2500 HD or GMC Sierra 2500 HD a more aggressive sound and a bolder look, this Gibson dual split cat-back exhaust system is a solid choice. This system is designed to replace your factory exhaust from the catalytic converter back, featuring 3.5-inch polished stainless steel slash-cut tips that exit straight out the back, complementing most bumper and hitch setups.

Gibson engineers this system with a baffled/chambered muffler that aims for an aggressive exterior tone without excessive interior drone, making it more comfortable on longer drives. The tubing is made from stainless steel and is mandrel-bent to ensure smooth airflow, which helps reduce backpressure. This improved flow can lead to a noticeable increase in torque and horsepower, with typical gains averaging between 15-20 horsepower. The Superflow™ muffler design contributes to this enhanced performance.

Installation is designed to be straightforward, utilizing a bolt-on process that doesn't require welding, making it a hassle-free upgrade. This system is built to last, featuring all stainless steel construction and backed by Gibson's Lifetime Limited Warranty, giving you confidence in its durability. While it offers a louder sound, especially under towing conditions, it's engineered to minimize interior noise.
