Gibson 08-09 Chevrolet Silverado 1500 LS 4.8L 2.25in Cat-Back Dual Extreme Exhaust - Aluminized

If you're looking to give your 2007-2009 Chevrolet Silverado 1500 LS with the 4.8L engine a more aggressive sound and a noticeable boost in performance, this Gibson Dual Extreme cat-back exhaust system is a solid choice. This system is designed to replace your factory exhaust from the catalytic converter back, exiting behind the rear tires at an aggressive angle for a bold street look.

Gibson tunes and tests their systems to ensure they not only sound powerful but also deliver real-world performance gains, with many users experiencing an average increase of 15-20 horsepower. The Superflow CFT muffler uses baffles and chambers instead of internal packing, which helps create a deep, aggressive exhaust note with minimal interior drone. The tubing is made from aluminized steel and is mandrel-bent to maintain consistent diameter for optimal exhaust flow. The system includes polished stainless steel slash-cut tips that clamp on for a clean finish.

Installation is straightforward thanks to the bolt-on design, and it uses factory-style hangers for a secure fit, meaning no welding is required. This system comes with all the necessary hardware for installation and is backed by Gibson's Lifetime Limited Warranty.
