A modification package designed for specific model year and engine configuration trucks typically involves the removal of certain emissions control components. These components often include the diesel particulate filter (DPF), exhaust gas recirculation (EGR) system, and selective catalytic reduction (SCR) system. This alteration aims to bypass factory-installed emission controls on a particular vehicle.
Historically, such modifications were pursued to enhance engine performance, improve fuel economy, and reduce maintenance costs associated with emissions control systems. Proponents argue that deleting these systems can lead to increased horsepower and torque, as well as decreased downtime for regeneration cycles and repairs. The removal of these systems may also be motivated by a desire to simplify the vehicle’s mechanical operation.
