@mosselmanturbo: Exhaust maxxing?🔥 The OPF, or Otto Particulate Filter, is the emission control component in modern petrol engines. Its job is to capture fine particulate matter from the exhaust gases and help the car meet strict emission regulations. While effective for emissions, it also creates significant backpressure in the exhaust system. When upgrading the exhaust, the OPF is often the main restriction. As long as it remains in place, it limits exhaust flow and suppresses the true character of the engine. That’s why addressing the OPF is the most important step when optimising the exhaust setup. Listen to the difference once the OPF restriction is removed. Exhaust flow improves significantly and the sound becomes deeper, sharper and far more pronounced, bringing out the engine’s full potential. To make this modification work correctly, the vehicle software must be adapted. We recalibrate the ECU so the car runs flawlessly without error codes or warning lights, while maintaining proper operation and drivability. Want to upgrade the sound and performance of your car?
