    Better Performance. Everyone wants more power and you can get just that for your 5.3L GMC Sierra by simply bolting on this 3” Single Aluminized Cat-Back Exhaust. Gibson has engineered it to help your engine make more power, especially improving low-end horsepower and torque. The included muffler is baffled and chambered, with no packing. By removing the restrictions found in the stock system, this cat-back also makes your truck sound more aggressive, all without creating interior drone when driving around town or on the highway.

    Solid Construction. Gibson makes this system out of an aluminized steel, and backs it up with a limited lifetime warranty. The piping measures 3 inches in diameter, while the tip is 4 inches.

    Straight Forward Design and Easy Installation. This Single Aluminized Cat-Back Exhaust keeps the same exit position as the stock system, so you don't have to cut any body panels. What's more, you don't need to cut or weld at all for the installation. All hardware, including factory-style hangers, come included.

    Application. This Gibson 3 in. Single Aluminized Cat-Back Exhaust System with a Single Side Exit is designed to be used on the 2007-2013 5.3L GMC Sierra's with the following cab and box configurations.
    • Regular Cab with the Standard Box
    • Extended Cab with the Standard Box
