ATLAS 5" Aluminized Steel DPF-Back Exhaust System
Upgrade exhaust flow and sound on your Ram 2500 / 3500 6.7L Cummins with the aFe POWER ATLAS 5-Inch DPF-Back Exhaust System. Engineered for durability, smooth tone, and reliable performance, this system replaces the factory DPF-back section with a high-flow, mandrel-bent design while retaining all factory emissions components.
High-Flow 5" Aluminized Steel Construction
Constructed from 5-inch mandrel-bent aluminized steel tubing, this exhaust system improves exhaust flow and reduces restriction compared to the factory system. The aluminized steel construction offers excellent durability and corrosion resistance for daily driving, towing, and work-duty applications.
Smooth, Refined Exhaust Tone
The ATLAS series is tuned to deliver a smooth, clean exhaust sound that enhances the Cummins engine note without excessive drone. This makes it ideal for long highway drives, towing, and commercial use while still improving performance and throttle response.
7" Black Stainless Steel Exhaust Tip
Finished with a 7-inch diameter black stainless steel clamp-on exhaust tip, this system adds an aggressive, modern appearance. The tip features a riveted aFe POWER logo plate, delivering a bold, premium look at the rear of the truck.
Direct Bolt-On Installation
Utilizing factory-style hangers, this DPF-back exhaust installs directly into the stock location with no cutting or modifications required. All necessary hardware is included for a hassle-free installation.
Precision Engineering & Weld Quality
Designed using state-of-the-art computer-aided design (CAD) for precise factory fitment and 100% MIG-welded for race-proven strength and long-term durability.
