Description
The aFe Power ATLAS 5" DPF-Back Exhaust System is engineered to deliver improved exhaust flow, enhanced performance, and aggressive styling for 2013–2018 Ram 2500 & 3500 6.7L Cummins diesel trucks. Designed and manufactured in Corona, California, this system combines durability, OE-quality fitment, and performance-driven engineering.
Constructed from 5-inch mandrel-bent aluminized steel tubing, this exhaust system maximizes exhaust flow by maintaining consistent diameter throughout the bends, reducing restriction and turbulence. The result is lower exhaust gas temperatures (EGTs), improved throttle response, and gains in horsepower and torque—without compromising reliability.
Installation is quick and hassle-free thanks to factory mounting locations, OE-style bayonet hangers, and high-quality band clamps. These components ensure a secure fit that remains stable under high vibration and heat conditions. An included extension pipe allows proper fitment on Crew Cab Long Bed models, making this system versatile across multiple configurations.
Completing the system is a massive 6-inch black stainless steel exhaust tip, featuring a laser-cut stainless steel aFe Power badge for a bold, aggressive appearance. The bayonet-style tip design securely retains the hanger bushing, ensuring long-term alignment and an OEM-like fit that does not shift over time.
This DPF-back exhaust system does not require a CARB EO number, making it an emissions-compliant upgrade that retains all factory emissions equipment while significantly improving exhaust efficiency and sound.
