The stock exhaust system of Mercedes-AMG A35 uses an OPF gasoline particulate filter and a catalyst converter, so the sound and audio are restricted. Although, canceling OPF can obviously increase the volume and make the sound more “exciting”, it also caused the risk of warning from Engine Check Light.

Furthermore, our OBDII valve control system can control the timing of the valve opening by itself, and force the valve to maintain the state of “open” or “closed”. However, it is also feasible to use the original valve control system, but it is impossible to control the timing of valve opening and closing, and it may cause side effects of the resonance due to the original valve opening angle of the control valve.
