Description
The aFe POWER Large Bore-HD 3.5" DPF-Back Exhaust System is engineered to deliver maximum exhaust flow, improved performance, and aggressive styling for 2016–2022 Chevrolet Colorado and GMC Canyon Diesel trucks equipped with the 2.8L Duramax engine.
This high-performance DPF-back exhaust system is constructed from 3.5-inch mandrel-bent 409 stainless steel tubing, designed to significantly reduce exhaust restriction while maintaining smooth exhaust gas flow. With optimized tubing diameter and smooth transition bends, this system provides up to a 40% increase in exhaust flow, helping to improve horsepower, torque, throttle response, and reduce exhaust gas temperatures (EGTs).
Designed for durability and a precise OE-style fit, the system utilizes high-quality stainless steel band clamps and OE-style bayonet hangers, ensuring proper alignment and long-term stability even under high heat and vibration. The exhaust installs using factory mounting locations, providing a clean, secure fit and a straightforward installation process.
Completing the system is a massive 5-inch diameter polished stainless steel intercooled exhaust tip, featuring integrated cooling vents to help reduce exhaust temperatures at the tailpipe. The tip is finished with a laser-cut stainless steel aFe POWER badge, delivering a bold, aggressive appearance that stands out.
This Large Bore-HD exhaust system is engineered and manufactured in Corona, California, offering proven performance, premium materials, and exceptional build quality.
