2007.5–2012 RAM 2500/3500 6.7L

Part #: 49-02016-B

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 offers a seamless upgrade that enhances your truck’s performance and sound without compromising durability or fitment.

Ideal for diesel truck owners seeking improved exhaust flow, the Atlas system delivers increased horsepower and torque while reducing exhaust gas temperatures (EGTs). Its direct-fit design ensures a hassle-free installation using all factory mounting points, making it a practical choice for enthusiasts who want reliable performance gains with minimal downtime.

Key Features

The aFe Atlas DPF-Back Exhaust System combines quality materials and smart engineering to optimize your RAM’s exhaust flow and durability. Key features include:

• 5-inch mandrel-bent aluminized steel tubing for smooth, unrestricted exhaust flow
• Precision-engineered smooth transition bends to minimize turbulence and maximize power
• High-quality OE-style band clamps and bayonet hangers for secure, leak-free connections
• Massive 7-inch wrinkle-black powder-coated exhaust tip with laser-cut stainless steel aFe power badge
• Drain port on the exhaust tip to prevent rust and corrosion buildup
• Utilizes all factory mounting locations for a direct bolt-on installation
• 360-degree sealing surface with OE-style flange and clamps for durability and leak prevention
• Manufactured in Corona, California to ensure premium quality and consistency

Construction & Design

This exhaust system is crafted from aluminized steel tubing that offers excellent corrosion resistance and long-lasting durability under harsh driving conditions. The 5-inch mandrel bends maintain consistent diameter throughout the system, reducing backpressure and promoting efficient exhaust scavenging. The wrinkle-black powder-coated 7-inch tip not only adds a bold visual statement but also features a drain port to extend the life of the exhaust by preventing moisture accumulation.

Every component is engineered for a perfect fit using factory mounting points, ensuring that the system integrates seamlessly with your RAM’s existing hardware. The use of OE-style band clamps and bayonet hangers guarantees a secure, rattle-free installation that maintains factory-level refinement.

Performance & Sound

The Atlas DPF-Back system is designed to improve exhaust flow, which can lead to noticeable gains in horsepower and torque. By reducing exhaust gas temperatures, it helps maintain engine efficiency and longevity. The system also enhances the exhaust note, delivering a deeper, more aggressive sound that complements the power and presence of your RAM 2500 or 3500 diesel truck without being overly loud or intrusive.

Installation & Fitment

Installation is straightforward and requires no cutting, welding, or modifications. The system uses all factory mounting locations and hardware, allowing for a quick and hassle-free bolt-on upgrade. This ensures that your truck maintains its factory alignment and fitment standards while benefiting from improved exhaust performance.
