Gibson 11-19 Chevrolet Silverado 2500 HD LT 6.0L 3.5in/3in Cat-Back Dual Split Exhaust - Aluminized

This Gibson cat-back dual split exhaust system is designed for your 2011-2019 Chevrolet Silverado 2500 HD or GMC Sierra 2500 HD, including 3500 HD models. It replaces your factory exhaust from the catalytic converter back, featuring 3.5-inch inlet and 3-inch outlet pipes with polished stainless steel slash-cut tips that exit straight out the back. This setup is built to give your truck a more aggressive, throaty sound, especially noticeable under towing conditions, while minimizing interior drone thanks to its baffled/chambered Superflow™ muffler with no internal packing.

The tubing is made from aluminized steel, which offers good corrosion resistance for a long service life, and it's mandrel-bent to maintain consistent pipe diameter for improved exhaust flow. By reducing backpressure, this system aims to increase torque and horsepower, with typical gains averaging between 15-20 horsepower. The design works with most bumpers, roll pans, and trailer hitches, making it a versatile option for many truck configurations. Installation is straightforward with a hassle-free, bolt-on design that requires no welding.

This exhaust system comes with polished stainless steel slash-cut tips and is backed by a Lifetime Limited Warranty from Gibson. It's a solid option if you're looking to change the sound and appearance of your heavy-duty truck.
