aFe ATLAS 5" Aluminized Steel DPF-Back Exhaust System
With 6" Polished Stainless Steel Tip | For 6.7L Cummins Ram Trucks (2007–2012)
Upgrade the performance and sound of your 6.7L Cummins-powered Ram with the aFe ATLAS DPF-Back Exhaust System. Constructed from 5-inch mandrel-bent aluminized steel tubing, this system provides improved exhaust flow, reduced backpressure, and lowered exhaust gas temperatures (EGTs) while maintaining long-term durability and OE-quality fitment.
The ATLAS exhaust is designed as a direct-fit DPF-back replacement, using all factory mounting points for an easy, no-modification installation. OE-style bayonet hangers, along with high-quality flanges and band clamps, deliver a secure, leak-free seal while ensuring precise exhaust alignment even under extreme heat and vibration.
Smooth mandrel bends allow for maximum flow with minimal turbulence, supporting gains in horsepower and torque while enhancing overall engine efficiency. Completing the system is a high-luster 6-inch polished 304 stainless steel slash-cut exhaust tip, featuring a drain port to prevent corrosion and a laser-cut stainless steel aFe Power badge for a bold, premium appearance.
Manufactured and engineered in Corona, California, the aFe ATLAS exhaust system delivers reliable performance, precise OE fitment, and exceptional value for your Ram 2500 or 3500.
