Key Features and Benefits

The aFe Large Bore HD Exhaust features 5" mandrel-bent 409 stainless steel tubing, providing maximum flow and reducing backpressure. This design allows for smoother transition bends, which minimize turbulence and increase horsepower, torque, and reduce exhaust gas temperatures (EGT's). The included 6" diameter polished intercooled tip with slash cut finish not only adds a sleek, high-performance look but also aids in further reducing EGT's for optimal engine health. The system is complete with high-quality band clamps for a leak-free seal and OE-style bayonet hangers that maintain a stable pipe location under high vibration and heat conditions, ensuring a hassle-free installation and long-lasting performance.

Practical Uses and Target Audience

Whether you're a daily driver or a heavy-duty truck enthusiast, the aFe Large Bore HD Exhaust is the perfect addition to your vehicle. This exhaust system is ideal for those seeking an upgrade that delivers both performance gains and a distinctive appearance. It is designed to fit various 2017-2019 Chevrolet and GMC models, including Silverado 2500/3500 HD and Sierra 2500/3500 HD, providing a wide range of applications. By improving airflow and reducing EGT's, this exhaust system can enhance the overall driving experience, ensuring your vehicle performs at its best while looking aggressive and stylish.
