Description
Sound and Power. When you step on the gas and your stock exhaust leaves you feeling weak, it may be time to upgrade the exhaust system. Gibson's Dual Extreme Cat-Back Exhaust System gives your Silverado 2500 HD Extended Cab a more powerful growl. This split side exit exhaust is a direct fit for the factory system and will increase the volume of your 5.0L coyote engine. Performance gains were also in mind with the production of this catback system. With average gains of 15-20 horsepower, you'll have more power you need to pass slower traffic or pull your trailer.
SFT SuperFlow Muffler. Gibson's SFT SuperFlow Muffler provides your Silverado 2500 HD Extended Cab a powerful deep sound at the tailpipe, while providing minimal interior drone. Featuring a baffled and chambered design, this muffler increases the volume efficiency to provide unrestricted flow without any internal packing. You may experience a louder exhaust sound under towing conditions.
Durable Construction. Proudly manufactured in the USA, this Gibson Exhaust System is constructed from 3 in. inlet / dual 2.5 in. outlet aluminized steel mandrel bent tubing for durability and corrosion resistance. This exhaust system features a single inlet/dual outlet SFT SuperFlow baffled and chambered muffler that connects to a pair of 4 in. polished T304 stainless tips exiting behind both rear passenger tires.
Direct Bolt-On Install. The Gibson Performance Cat-Back Exhaust System is designed to be a direct bolt-on install using the factory hanger locations. You only need access to basic hand tools, as the system doesn't require any modifications. The kit includes all of the necessary hardware and clamps for a hassle free installation.
Lifetime Warranty. Gibson ensures quality craftsmanship of their headers with a Lifetime Limited Warranty. Some exclusions apply, please see manufacturer's warranty for complete details and exclusions.
Application. This Gibson 3 in. / 2.5 in. Dual Extreme Cat-Back Exhaust System is specifically designed to fit on the all 2001-2006 Silverado 2500 HD Extended Cab models.
