Description
aFe ATLAS 5" Aluminized Steel DPF-Back Exhaust System
With 7" Wrinkle-Black Tip | For 6.7L Cummins Ram Trucks (2007–2012)
Enhance both performance and appearance of your 6.7L Cummins-powered Ram with the aFe ATLAS DPF-Back Exhaust System. Built for durability, improved exhaust flow, and OE-quality fitment, this system features 5-inch mandrel-bent aluminized steel tubing that reduces backpressure, improves exhaust velocity, and helps lower exhaust gas temperatures (EGTs).
Designed as a direct-fit DPF-back replacement, the ATLAS exhaust installs using all factory mounting locations for a fast, hassle-free installation with no cutting or modifications required. OE-style bayonet hangers, along with high-quality flanges and band clamps, provide a secure, leak-free seal and maintain proper exhaust alignment under high heat and vibration.
Smooth mandrel bends promote efficient airflow with minimal turbulence, supporting gains in horsepower and torque while improving overall engine efficiency. Completing the system is a massive 7-inch wrinkle-black powder-coated exhaust tip, featuring a riveted, laser-cut stainless steel aFe Power badge for an aggressive, performance-driven appearance. An integrated drain port helps prevent moisture buildup and corrosion over time.
Engineered and manufactured in Corona, California, the aFe ATLAS exhaust system delivers dependable performance, precise fitment, and outstanding value for Cummins owners.
