Product Details
This Gibson cat-back exhaust system is built with stainless steel mandrel-bent tubing, a design that helps reduce backpressure and improve exhaust flow. It's designed to fit 2021-2025 Chevrolet Silverado 2500 HD and GMC Sierra 2500 HD trucks with the 6.6L engine, Crew Cab, and Long Bed configuration. The system features a baffled/chambered muffler with no internal packing, known as the Superflow™ CFT Muffler, which aims to provide a mild sound level inside the cabin during normal driving but becomes more aggressive when you're towing or under load.
The dual split rear exit with polished stainless steel slash-cut tips gives your truck a distinct look. Gibson states that this system can result in an average gain of 15-20 horsepower. Installation is straightforward thanks to the bolt-on design, which uses factory-style hangers and includes all necessary hardware, meaning no welding is required. This exhaust works with most bumpers, roll pans, and trailer hitches, making it a practical choice for work or play.
Gibson backs this exhaust system with a Lifetime Limited Warranty, offering peace of mind for your investment. If you're looking to improve your truck's exhaust note and flow without excessive interior noise, this Gibson system is a solid option.
