Description
The aFe POWER ATLAS 3.5" DPF-Back Exhaust System delivers improved exhaust flow, enhanced performance, and aggressive styling for 2016–2022 Chevrolet Colorado and GMC Canyon Diesel trucks equipped with the 2.8L Duramax engine. Designed for those seeking a durable, cost-effective alternative to stainless steel, this system is constructed from 3.5-inch mandrel-bent aluminized steel tubing to provide long-lasting corrosion resistance while maximizing exhaust efficiency.
Engineered for performance, the ATLAS exhaust system increases flow by up to 40%, improving horsepower, torque, and throttle response while reducing exhaust gas temperatures (EGTs). The system features smooth transition bends to minimize turbulence and optimize flow.
For a secure, factory-style fit, this system uses OE-style bayonet hangers and high-quality band clamps and installs using all factory mounting locations, providing a stable, hassle-free installation.
The exhaust finishes with a 5-inch black stainless steel intercooled tip, featuring integrated vents to lower tailpipe temperatures and a laser-cut aFe POWER stainless steel logo plate for a bold, aggressive appearance. Please note that installation requires cutting behind the DPF unit.
Engineered and manufactured in Corona, California, the ATLAS exhaust system delivers proven performance, reliable fitment, and aggressive style for full-size mid-duty diesel trucks.
