OE-Style Fitment and Construction

This exhaust pipe is manufactured with precision bending and fixture checking to help ensure accurate alignment during installation. It is compatible with 2010 Dodge Ram 2500 rear OE design applications, 2010 Dodge Ram 3500 rear long bed OE design applications, 2011-2012 Ram 2500 rear OE design applications, and 2011-2012 Ram 3500 rear OE design or cut-to-fit rear applications. This part cross-references Mopar 52122498AA for the same application. Walker 53979 is a practical replacement choice when servicing the rear exhaust on Ram 2500, Ram 3500, and Dodge Ram trucks.

Common Issues This Part Can Address

• Rusted or corroded rear exhaust pipe sections
• Cracked or leaking exhaust tubing
• Damaged OE-style pipe routing at the rear of the system
• Restricted exhaust flow caused by deteriorated pipe walls
• Fitment problems from bent or mismatched replacement tubing

Installation Notes and Tips

Verify the vehicle year, model, rear position, and OE design notes before ordering. Confirm the 4-inch inlet and outlet dimensions match the existing exhaust connection points, and compare the 31-inch length to the original pipe before installation. For 2011-2012 Ram 3500 rear applications marked cut to fit, final trimming may be required to match the vehicle configuration.
