aFe ATLAS 5" Aluminized Steel DPF-Back Exhaust System
With 6" Wrinkle-Black Stainless Steel Tip | For 6.7L Cummins Ram 2500 & 3500 (2013–2018)
Upgrade your 6.7L Cummins-powered Ram 2500 or 3500 with the aFe ATLAS 5" DPF-Back Exhaust System, engineered for superior flow, durability, and aggressive styling. Constructed from 100% MIG-welded 5" mandrel-bent aluminized steel tubing, this exhaust system is designed to reduce backpressure, lower exhaust gas temperatures (EGTs), and increase overall engine efficiency.
The ATLAS system features a specially formed end connection that attaches directly to the DPF, ensuring a precise, leak-free fit. OE-style bayonet hangers maintain proper pipe alignment during high heat and vibration, delivering a stable, OE-quality installation that won’t change over time.
Smooth mandrel bends optimize airflow while minimizing turbulence, increasing horsepower and torque. The system is finished with a massive 6" wrinkle-black powder-coated 304 stainless steel exhaust tip, complete with a drain port to prevent rust and corrosion, and a riveted laser-cut stainless steel aFe Power badge for a bold, performance-driven appearance.
Using all factory mounting locations, this exhaust system provides quick, hassle-free installation with a perfect fit for wheelbase configurations of 160" and 160.5".
Manufactured and engineered in Corona, California, the aFe ATLAS exhaust system delivers OE fitment, lasting durability, and an aggressive style for your Cummins truck.
