Product Details
If you're looking to give your 2007-2009 Chevrolet Silverado 2500 HD a more aggressive sound and a bolder appearance, this Gibson Dual Extreme cat-back exhaust system is a solid choice. Designed specifically for trucks with the 6.0L engine, this system replaces your factory exhaust from the catalytic converter back, exiting behind the rear tires at an aggressive angle for a powerful street presence. You can expect a mean performance sound that’s tuned for street use, complementing the truck's rugged look.
This system is constructed from durable stainless steel, featuring mandrel-bent tubing to ensure smooth exhaust flow. The heart of the system is Gibson's Superflow™ CFT muffler, which uses a baffled and chambered design without internal packing, contributing to its aggressive tone while minimizing interior drone. It also includes polished stainless steel slash-cut tips that clamp on for a clean finish. Gibson has dyno-tuned and tested this system, reporting average gains of 15-20 horsepower, which should make a noticeable difference in throttle response.
Installation is straightforward thanks to its bolt-on design, meaning no welding is required, and it utilizes factory-style hangers for a secure fit. This Gibson cat-back exhaust system is backed by a Lifetime Limited Warranty, giving you confidence in its longevity and performance. If you want an extreme look and sound for your Silverado HD, this system delivers.
