The aFe MACHForce XP Cat-Back Exhaust System is tailored for the `09-`13 GMC Sierra, offering an impressive upgrade to your vehicle's performance. Its sleek polished stainless-steel design isn't just about looks—this exhaust is built to endure even the toughest driving conditions.
Crafted from 4-inch mandrel bent 409 stainless steel tubing, the MACHForce XP is engineered to enhance exhaust flow significantly. This improvement leads to noticeable increases in horsepower and torque, while also contributing to lower exhaust gas temperatures (EGTs). The exhaust includes a 24-inch long muffler designed to produce a deep, aggressive sound, unleashing the full potential of your GMC Sierra. Thanks to its OE style bayonet hangers, installation is straightforward, ensuring your exhaust system remains stable under high vibration and heat conditions.
