Description
aFe ATLAS 5" Aluminized Steel DPF-Back Exhaust System
For 6.7L Cummins Ram Trucks (2007–2012)
Upgrade the exhaust performance of your 6.7L Cummins-powered Ram with the aFe ATLAS DPF-Back Exhaust System. Designed to deliver improved exhaust flow, reduced backpressure, and long-term durability, this system is constructed from 5-inch mandrel-bent aluminized steel tubing for consistent performance at an excellent value.
The ATLAS exhaust system is engineered as a direct-fit DPF-back replacement, utilizing all factory mounting locations for a straightforward, hassle-free installation with no cutting or modification required. OE-style bayonet hangers, along with premium flanges and band clamps, ensure proper pipe alignment, vibration control, and a secure, leak-free seal under demanding diesel operating conditions.
Smooth mandrel bends promote efficient exhaust flow while minimizing turbulence, helping to increase horsepower and torque while lowering exhaust gas temperatures (EGTs). The result is improved engine efficiency, enhanced throttle response, and a refined exhaust note without excessive drone.
Engineered and manufactured in Corona, California, the aFe ATLAS DPF-Back Exhaust System offers the ideal balance of performance, fitment, and value for daily-driven and work-ready Cummins trucks.
