aFe Atlas Exhaust System

Fits Most Dodge/Ram 6.7L Diesel/5.9L Diesel (07-12)

Part #: 49-02016

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 direct-fit solution that enhances your truck’s performance without compromising reliability or fitment. Ideal for diesel enthusiasts seeking improved exhaust flow, increased horsepower and torque, and reduced exhaust gas temperatures (EGTs), the Atlas exhaust system delivers a balanced upgrade that combines durability with performance gains.

Built with precision and quality in mind, this exhaust system is perfect for those who want a hassle-free installation experience while upgrading their RAM’s exhaust for better efficiency and sound characteristics.

Key Features

The aFe Atlas DPF-Back Exhaust System incorporates advanced design elements and quality components to ensure optimal performance and longevity. Key features include:

• 5-inch mandrel-bent aluminized steel tubing for smooth exhaust flow and corrosion resistance
• DPF-back design that replaces the exhaust system from the factory Diesel Particulate Filter outlet to the rear
• Precision-engineered smooth transition bends to minimize turbulence and maximize horsepower and torque
• High-quality band clamps for secure and leak-free connections
• OE-style bayonet hangers that utilize all factory mounting points for a perfect fit
• Direct bolt-on installation with no modifications required
• Manufactured in aFe’s Corona, California facility, ensuring strict quality control
• Durable aluminized steel construction for long-lasting corrosion protection
• Designed to lower exhaust gas temperatures (EGTs) for improved engine efficiency

Construction & Design

The Atlas exhaust system is crafted from 5-inch aluminized steel tubing, chosen for its excellent resistance to rust and heat. The mandrel-bent tubing maintains consistent diameter through bends, preventing flow restrictions and promoting efficient exhaust scavenging. This design reduces backpressure and turbulence, which helps the engine breathe better and perform more efficiently.

All components are engineered to fit precisely using the original factory mounting locations, including OE-style bayonet hangers and high-quality band clamps. This ensures a secure, rattle-free installation that maintains the vehicle’s factory alignment and appearance. The aluminized steel finish provides a durable protective layer, extending the life of the exhaust system in harsh road and weather conditions.

Performance & Sound

The aFe Atlas DPF-Back Exhaust System is designed to improve exhaust flow, which can translate into noticeable gains in horsepower and torque. By reducing exhaust gas temperatures (EGTs), it helps maintain engine efficiency and longevity under demanding conditions. The smooth transition bends and optimized piping diameter reduce turbulence, allowing the turbocharger to spool more efficiently and respond quicker.

While this system does not include a tip, it delivers a refined exhaust note that enhances the factory sound without being overly loud or aggressive. This makes it an excellent choice for drivers who want improved performance and a subtle, deep exhaust tone.

Installation & Fitment

This exhaust system is designed for a direct bolt-on installation using all factory mounting points, making it a straightforward upgrade for the 2007.5 to 2012 RAM 2500 and 3500 6.7L diesel trucks. No cutting, welding, or modifications are required, allowing for a quick and hassle-free installation process. The system uses OE-style bayonet hangers and high-quality band clamps to ensure a secure fit and proper alignment.

What's Included

• 5" aluminized steel DPF-back exhaust piping
• High-quality band clamps
• OE-style bayonet hangers
• Installation hardware
• Detailed installation instructions
