aFe Atlas DPF-Back Exhaust System

2007.5–2012 RAM 2500/3500 6.7L

Part #: 49-02016-P

Overview

The aFe Atlas 5" Aluminized Steel DPF-Back Exhaust System is engineered specifically for the 2007.5 to 2012 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 enhances exhaust flow while maintaining a clean and durable construction. It is ideal for diesel truck owners seeking improved performance, reduced exhaust gas temperatures, and a refined exhaust tone without compromising reliability or fitment.

Built to deliver a balance of power gains and longevity, the Atlas exhaust system is perfect for enthusiasts and professionals who demand quality and ease of installation. Its design focuses on maximizing flow efficiency and durability, making it a solid upgrade for daily drivers and work trucks alike.

Key Features

This exhaust system incorporates advanced engineering and quality materials to ensure superior performance and durability. Key features include:

• 5-inch mandrel-bent aluminized steel tubing for maximum exhaust flow and minimal restriction
• Smooth transition bends that reduce turbulence, helping increase horsepower and torque while lowering exhaust gas temperatures (EGTs)
• High-quality OE-style band clamps and bayonet hangers for secure, vibration-free mounting
• Utilizes all factory mounting locations for a straightforward, hassle-free installation process
• Massive 6-inch polished 304 stainless steel exhaust tip with laser-cut aFe Power badge for a premium appearance
• Drain port integrated into the tip to prevent rust and corrosion buildup
• OE-style flange and band clamps providing a complete 360-degree sealing surface to prevent leaks
• Manufactured in aFe’s Corona, California facility, ensuring strict quality control and craftsmanship

Construction & Design

The Atlas DPF-Back Exhaust System is constructed from aluminized steel tubing, chosen for its excellent resistance to corrosion and heat. The 5-inch diameter tubing is mandrel-bent to maintain consistent internal diameter through bends, which minimizes flow restrictions and turbulence. This design promotes efficient exhaust scavenging and reduces backpressure, contributing to improved engine performance and longevity.

The exhaust tip is crafted from polished 304 stainless steel, offering both aesthetic appeal and enhanced durability. The inclusion of a drain port at the bottom of the tip helps prevent moisture accumulation, reducing the risk of rust and corrosion over time. The system’s flanges and clamps are designed to replicate OE standards, ensuring a tight, leak-free fit and long-lasting reliability.

Performance & Sound

By optimizing exhaust flow and reducing backpressure, the aFe Atlas DPF-Back Exhaust System helps increase horsepower and torque output while lowering exhaust gas temperatures. This can contribute to improved engine efficiency and potentially extend the life of turbo components. The system also delivers a deeper, more aggressive exhaust note compared to stock, enhancing the driving experience without excessive noise or drone.

Installation & Fitment

The Atlas exhaust system is designed for a direct bolt-on installation using all factory mounting points, eliminating the need for cutting, welding, or modifications. OE-style bayonet hangers and band clamps simplify the installation process, making it accessible for both professional installers and experienced DIY enthusiasts. This ensures a secure fit and quick turnaround time, allowing you to get back on the road faster.
