DPF Back

A DPF back is a performance upgrade for diesel vehicles that replaces the vehicle's diesel particulate filter (DPF). The DPF traps soot and other particles from the exhaust, but it can clog over time, reducing engine performance and fuel efficiency. A DPF back removes the filter entirely, allowing for better exhaust flow and potentially increasing horsepower and torque. However, it's important to be aware that DPF backs are illegal for use on street vehicles in many areas due to increased emissions.  Be sure to check your local regulations before installing one.
