aFe Atlas DPF-Back Exhaust System
2013–2018 RAM 2500/3500 6.7L
Part #: 49-02039-B
Overview
The aFe Atlas 5" Aluminized Steel DPF-Back Exhaust with Black Tip is engineered specifically for the 2013–2018 RAM 2500 and 3500 models equipped with the 6.7L engine. Designed to replace the factory exhaust from the Diesel Particulate Filter (DPF) back, this system offers a direct-fit upgrade that enhances your truck’s performance and sound without compromising reliability or durability.
Ideal for diesel truck owners seeking improved exhaust flow and a more aggressive exhaust note, the Atlas DPF-Back exhaust delivers a balance of power gains, reduced exhaust gas temperatures, and a clean, professional appearance with its sleek black tip finish.
Key Features
This exhaust system combines quality materials and thoughtful engineering to provide a superior upgrade for your RAM diesel truck:
- Constructed from 5-inch mandrel-bent aluminized steel tubing for durability and corrosion resistance
- Smooth transition bends reduce turbulence, optimizing exhaust flow for increased horsepower and torque
- Utilizes high-quality band clamps and OE-style bayonet hangers for secure and vibration-free mounting
- Maintains all factory mounting locations for a hassle-free, bolt-on installation
- Features a stylish black exhaust tip that complements the aggressive look of your truck
- Designed and manufactured in aFe’s Corona, California facility, ensuring strict quality control
- DPF-back design preserves factory emissions components while enhancing performance
Construction & Design
The Atlas exhaust system is built from aluminized steel, chosen for its excellent resistance to rust and corrosion, especially important in harsh road and weather conditions. The 5-inch diameter tubing is mandrel-bent to maintain consistent internal diameter through bends, preventing flow restrictions and maximizing exhaust gas velocity.
Every joint and connection is engineered to fit precisely using OE-style bayonet hangers and premium band clamps, ensuring a secure fit that minimizes rattles and vibrations. The black tip is finished with a durable coating that resists discoloration and wear, adding a refined touch to your truck’s rear appearance.
Performance & Sound
By improving exhaust flow and reducing backpressure, the Atlas DPF-Back exhaust helps your 6.7L Cummins engine breathe more efficiently. This results in noticeable gains in horsepower and torque, as well as lower exhaust gas temperatures (EGTs), which contribute to engine longevity and reliability.
The exhaust note is enhanced to deliver a deeper, more aggressive sound without being overly loud or drone-prone, providing an enjoyable driving experience whether on the highway or off-road.
Installation & Fitment
This exhaust system is designed for a direct bolt-on installation using all factory mounting points, making the upgrade straightforward and quick. No cutting, welding, or additional modifications are required, allowing you to maintain the integrity of your truck’s original exhaust layout.
Compatible exclusively with 2013 through 2018 RAM 2500 and 3500 models equipped with the 6.7L Cummins engine, the Atlas DPF-Back exhaust ensures a perfect fit and reliable performance.

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!
