Another exhaust gas cleaning system, most used in gasoline/flex fuel vehicles. When seeking a Stage 2 reprogramming where there is a need to replace the vehicle's original downpipe, it is necessary to manipulate this system so that the vehicle works correctly despite the physical removal of the filter.
The vehicle's catalytic converter probe is disconnected, when available, allowing it to be removed. It is required for Stage 2 on turbo vehicles.
