Gibson 99-05 Chevrolet Silverado 1500 Base 4.3L 2.5in Cat-Back Super Truck Exhaust - Stainless

If you're looking to give your 1999-2007 Chevrolet Silverado or GMC Sierra a more aggressive sound and a noticeable boost in performance, this Gibson Super Truck Cat-Back Exhaust System is a solid choice. Designed specifically for trucks like the Silverado 1500, 2500, and their Sierra counterparts, this system replaces your factory exhaust from the catalytic converter back, giving you a bolder tone and improved flow. It's built with stainless steel tubing and tips for durability and a clean look, exiting in front of the rear tires for a classic sport truck appearance.

This Gibson system features a baffled/chambered muffler, which means it achieves its aggressive, deep rumble without relying on internal packing that can break down over time. You can expect an improved acceleration feel and, based on Gibson's testing, an average gain of 10-15 horsepower and 15-20 lb-ft of torque. The 2.5-inch stainless steel, mandrel-bent tubing ensures consistent exhaust flow, while the Superflow™ muffler is designed to minimize interior drone, making it more comfortable for daily driving despite its aggressive exterior sound. The stainless steel sport truck tips complete the look, exiting in front of the rear wheels.

Installation is straightforward thanks to the bolt-on design, meaning no welding is required, and it fits right onto your existing factory hanger locations. This system is backed by a Lifetime Limited Warranty from Gibson, offering peace of mind. Please note that this system is not recommended for towing applications and its noise level may exceed 95 decibels, so check local regulations. It's a well-built option for truck owners wanting a significant upgrade in sound and performance.
