    Aggressive Power and Sound. When you need to take your 6.2L Sierra's power and sound to the next level, this Gibson 3.5 in. Single Stainless Cat-Back Exhaust System is the only way to go. It's a single-side exit exhaust that produces an aggressively deep, throaty exhaust note that gets your blood pumping. Meanwhile, the sound inside the cab is kept at a minimum. Not only that, but you'll enjoy an increase in torque and horsepower at low-end RPMs. This is ideal for heavy-duty towing, climbing, and passing.

    SuperFlow Muffler. As if quality sound and performance weren't enough, the Gibson 3.5 in. Single Cat-Back Exhaust System takes it to the next level with a SuperFlow muffler. The muffler features a baffled and chambered design, which increases volume efficiency and removes flow restrictions. That means more useable power and better acceleration, with an average gain of up to 15 horsepower and up to 20 foot-pounds of increased torque.

    Quality Design and Construction. This Gibson 3.5 in. Single Cat-Back Exhaust System features 3 in. stainless steel, mandrel-bent tubing, and the single inlet/outlet muffler that connects to a 4-in. polished, slash-cut, stainless steel tip exiting behind the rear tire. The stainless-steel components give this system outstanding durability, leak protection, and corrosion resistance.

    Direct Bolt-On Installation. This single-side exit exhaust system fits your factory system with a direct, bolt-on design. With no welding required, it's a hassle-free install that only takes a couple of hours.

    Application. The Gibson 3.5 in. Single Stainless Cat-Back Exhaust System is designed to fit perfectly on your 2011-2013 6.2L GMC Sierra's with the following cab and box configurations.
    • Extended Cab with the Standard Box
    • Crew Cab with the Short Box
