Product Details
This Gibson cat-back exhaust system is designed to fit your 2011-2019 Chevrolet Silverado 2500 HD or GMC Sierra 2500 HD with the 6.0L engine. You'll get the complete system, including all the necessary hardware and factory-style hangers, to make installation straightforward. The dual split rear exit with polished stainless steel slash-cut tips gives your truck a more aggressive look out back, and it's designed to work with most bumpers, roll pans, and trailer hitches.
Inside this system is Gibson's Superflow muffler, which uses a baffled and chambered design without internal packing. This setup is tuned to produce a deeper, more aggressive exhaust note, especially noticeable under load like when towing, while minimizing interior drone. The tubing itself is made from stainless steel and is mandrel-bent to ensure consistent diameter throughout, which helps reduce backpressure compared to the stock system. This improved flow can lead to a noticeable increase in torque and horsepower.
Installation is designed to be a hassle-free bolt-on process, meaning no welding is required. Gibson backs this system with a lifetime limited warranty, giving you confidence in its durability and performance for years to come.
