    Minimizes Interior Drone. Give your truck a more aggressive sound sans the annoying drone with the Gibson Dual Sport Stainless Cat-Back Exhaust System. The baffled and muffled chamber included in this system is designed to produce a deep, throaty tone — an impressive sound that is preserved by the attached 2.25" diameter mandrel-bent tubing.

    Robust Construction. One of the most visually appealing components of this cat-back system is a clamp-on polished T304 stainless tip. Measuring 2.25" in diameter and sporting a round slash-cut style, this tip is a perfect complement for any truck. Aside from its appearance, the tip and the attached tubing allow freer exhaust flows, improving your truck's torque and HP. And because these components are both made of stainless steel, they'll resist rust and corrosion for a long time.

    Improved Look with Minimal Effort. The Gibson Dual Sport Stainless Cat-Back Exhaust System attaches to the underside of your truck using a bolt-on system. It's easy to install, comes in a complete kit and, once you're finished with the installation, looks like it's been done by a professional.

    Application. This Gibson 3 in. / 2.25 in. Dual Sport Stainless Cat-Back Exhaust System with a Dual Side Exit is designed to be used on the 2007-2013 5.3L GMC Sierra's with the following cab and box configurations.
