• 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.
