An aftertreatment system comprises an aftertreatment component. An outlet sensor is positioned downstream of the aftertreatment component. A controller is communicatively coupled to the outlet sensor. The controller is configured to interpret an outlet signal from the outlet sensor. The outlet signal is indicative of a performance of the aftertreatment component. The controller determines if the aftertreatment component has deactivated. In response to determining that the aftertreatment component has deactivated, the controller provides a catalyst active material to at least a portion of the aftertreatment component. The catalyst active material coats at least the portion of the aftertreatment component so as to remanufacture the aftertreatment component.
