aFe Atlas 5" Aluminized Steel DPF-Back Exhaust
2013–2018 RAM 2500 / 3500 6.7L Crew Cab
Part #: 49-02051-1B
Overview
The aFe Atlas 5" Aluminized Steel DPF-Back Exhaust is engineered specifically for the 2013 to 2018 RAM 2500 and 3500 models equipped with the 6.7L Cummins engine and Crew Cab configuration. Designed to replace the restrictive factory exhaust components from the Diesel Particulate Filter (DPF) back, this system enhances exhaust flow while maintaining a clean, OE-style appearance. It is an ideal upgrade for diesel truck owners seeking improved performance, durability, and a subtle yet aggressive exhaust tone without compromising reliability or fitment.
Built to optimize exhaust gas evacuation, this DPF-back exhaust reduces backpressure and supports better engine efficiency. It is perfect for enthusiasts who want to maximize their truck’s power potential while retaining a factory-like installation experience.
Key Features
The aFe Atlas DPF-Back Exhaust combines robust construction with thoughtful design to deliver lasting performance and ease of installation. Key features include:
- 5-inch aluminized steel tubing for enhanced durability and corrosion resistance
- 4-inch 409 stainless steel tubing in critical sections for smooth exhaust flow and longevity
- Large bore design with smooth mandrel bends to minimize restrictions and optimize gas flow
- OE-style band clamps and bayonet-style hangers for a secure, factory-like fitment
- Black powder-coated exhaust tip for a sleek, aggressive finish that resists rust and discoloration
- Direct bolt-on replacement for the factory DPF-back section, requiring no cutting or welding
- Compatible with stock emissions equipment to maintain compliance and reliability
Construction & Design
The exhaust system features a combination of aluminized steel and 409 stainless steel tubing, carefully selected for their corrosion resistance and strength under high-heat conditions. The aluminized steel provides excellent protection against rust and environmental damage, while the stainless steel sections ensure smooth exhaust flow and durability where it matters most. Mandrel-bent tubing preserves consistent diameter through bends, reducing turbulence and backpressure for improved engine breathing.
Attention to detail is evident in the use of OE-style band clamps and bayonet hangers, which allow for a clean, secure installation that aligns perfectly with factory mounting points. The black powder-coated tip not only adds a refined aesthetic but also protects against the elements, ensuring the exhaust maintains its appearance over time.
Installation & Fitment
This aFe Atlas DPF-Back Exhaust is designed as a direct bolt-on replacement for the factory DPF-back section on 2013–2018 RAM 2500 and 3500 6.7L Crew Cab trucks. The system installs easily using the included OE-style band clamps and bayonet hangers, requiring no cutting, welding, or modifications. This ensures a hassle-free upgrade that preserves factory fitment and alignment, making it accessible for both professional installers and experienced DIY enthusiasts.

What does the Available to Promise date mean?
ETA stands for Estimated Time of Arrival. The date shown is calculated using our Available-to-Promise (ATP) system, which tracks real-time supplier commitments to determine when a product is expected to be available for delivery. Specifically, the date is calculated by adding 9 business days from the date a supplier has committed to ship the product, representing a worst-case scenario for when we can expect to receive inventory.
Please note: The ETA is an estimate, not a guarantee. While we work closely with our suppliers to keep dates as accurate as possible, delays due to shipping carriers, weather, customs, or supplier-side issues may occasionally push the actual arrival beyond the date shown. Likewise, inventory may arrive sooner than the ETA in many cases. If you would like to be notified for when this item arrives, sign up for our back in stock notifications!
