Gibson 99-05 Chevrolet Silverado 1500 Base 4.3L 2.5in Cat-Back Dual Extreme Exhaust - Aluminized

Starting with 2.5-inch aluminized steel tubing, this Gibson Dual Extreme cat-back system is built for trucks that need to make a statement. It's designed to fit a range of popular GM trucks, including the 1999-2006 Chevrolet Silverado 1500 and GMC Sierra 1500, as well as the 2007 Classic models. The system exits behind the rear tires at an aggressive angle, giving your truck a bold, performance-oriented look that matches its sound.

At the heart of this system is Gibson's Superflow CFT muffler, which uses a baffled and chambered design without internal packing. This approach creates a powerful, aggressive exhaust tone that’s dyno-tuned and tested for street performance, with reported gains of 15-20 horsepower. Despite the aggressive sound, Gibson engineers worked to minimize interior drone, so you can still have a comfortable drive. 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, meaning no welding is required. All necessary hardware and factory-style hangers are included to make the process as hassle-free as possible. This system is backed by a Lifetime Limited Warranty, giving you confidence in its durability and performance for years to come.
