This refers to a collection of aftermarket components designed to remove or bypass certain emissions control systems present on 6.7-liter Ford diesel engines, typically found in Super Duty trucks. These systems often include the diesel particulate filter (DPF), exhaust gas recirculation (EGR), and selective catalytic reduction (SCR) systems. As an example, the kit may contain pipes to replace the DPF, block-off plates for the EGR system, and tuning software to reprogram the engine control unit (ECU).
The implementation of this modification is often driven by perceived enhancements to engine performance, fuel economy, and long-term reliability. The removal of restrictive emissions equipment can potentially increase horsepower and torque. Furthermore, eliminating components prone to failure may reduce maintenance costs and downtime. Historically, these modifications gained traction as a means to circumvent increasingly stringent emissions regulations, particularly in off-road or competition applications. However, it’s crucial to acknowledge that altering or removing federally mandated emissions control devices is generally illegal for on-highway vehicles.
