This refers to aftermarket components designed to remove the factory-installed emissions control systems on certain model year Ram 1500 trucks equipped with the 3.0L EcoDiesel engine. These systems typically include the diesel particulate filter (DPF), exhaust gas recirculation (EGR) system, and diesel oxidation catalyst (DOC). The practice involves physically removing these components and often requires reprogramming the engine control unit (ECU) to prevent error codes and maintain engine functionality.
The motivation behind this modification often stems from concerns regarding the reliability and maintenance costs associated with the original equipment manufacturer (OEM) emissions control systems. Potential benefits cited include improved fuel economy, increased engine performance, and reduced maintenance requirements. Historically, this practice has gained traction as owners seek to circumvent the complexities and potential failure points of the factory emissions systems.
