Description
The aFe POWER ATLAS 3.5" Aluminized Steel DPF-Back Exhaust System with Polished Tip is designed for 2016–2022 Chevrolet Colorado and GMC Canyon Diesel trucks equipped with the 2.8L Duramax engine. This performance-oriented DPF-back exhaust system delivers up to 40% increased exhaust flow, improving horsepower, torque, throttle response, and lowering exhaust gas temperatures (EGTs) for optimized engine performance.
Constructed from 3.5-inch mandrel-bent aluminized steel tubing, the ATLAS exhaust combines durability with efficient airflow. Smooth transition bends reduce turbulence, maximizing performance while maintaining a factory-style fit.
Installation is simple and hassle-free, using all factory mounting locations with OE-style bayonet hangers and high-quality band clamps for a secure, stable fit. The system requires cutting behind the DPF unit, but is designed to maintain precise alignment and long-term reliability.
Finishing the exhaust is a 5-inch polished stainless steel intercooled slash-cut tip, featuring vents to reduce exhaust gas temperatures at the tailpipe and a laser-cut aFe POWER stainless steel badge for a bold, aggressive appearance.
Engineered and manufactured in Corona, California, the ATLAS exhaust system delivers proven performance, durability, and eye-catching style for mid-duty diesel trucks.
