      Boosts Your Truck's Performance. With the aFe Rebel Series 3 in. to 2.5 in. Middle Side Exit Cat-Back Exhaust with Polished Tips installed in your GMC Sierra, you can expect an extra dose of performance. Tests in a controlled environment show that the system provides horsepower gains of up to 14 horsepower and 17 lb/ft of torque.

      A Louder and More Aggressive Exhaust Noise. The Rebel Series 3 in. to 2.5 in. Cat-Back Exhaust uses a free-flow muffler designed to absorb your exhaust noise's high pitch tones. This results in a deeper and more aggressive noise that reflects the difference in performance.

      Superior Construction that's Built to Last. All aFe exhaust systems are engineered and manufactured in Corona, CA, ensuring the line's adherence to high standards of quality. The system's stainless steel parts offer stronger resistance to the corrosive toxic elements in your exhaust gas. Meanwhile, durable band clamps are used for 360-degree sealing to help eliminate leaks. The effect is a longer lasting system that requires minimal maintenance checks.

      Application. The aFe Rebel Series 3 in. to 2.5 in. Middle Side Exit Cat-Back Exhaust with Polished Tips is designed to be used on the 2009-2013 4.8L GMC Sierra's with the following cab and box configuration.
