Description
ATLAS 5" Aluminized Steel DPF-Back Exhaust System – RAM 2500 / 3500 6.7L Cummins (2013–2018)
Upgrade your diesel truck with the aFe POWER ATLAS 5-Inch DPF-Back Exhaust System, engineered to deliver improved exhaust flow, reduced backpressure, and aggressive styling for 2013–2018 RAM 2500 and 3500 trucks equipped with the 6.7L Cummins diesel engine. Built from durable aluminized steel and designed for OE-quality fitment, this system enhances performance while maintaining long-term reliability.
The ATLAS exhaust utilizes large-diameter mandrel-bent tubing and smooth transition bends to optimize airflow, helping lower exhaust gas temperatures (EGTs) while supporting horsepower and torque gains. Designed as a true bolt-on system, it installs easily using factory mounting points and OE-style hardware for a secure, rattle-free fit.
