An aftertreatment device of a vehicle exhaust system includes an aftertreatment device. The aftertreatment device includes a body defining an inlet cone, an outlet cone, and a cavity therebetween. A heating element is disposed in the cavity. A catalyst is disposed in the cavity downstream of the heating element. A recirculation loop has a conduit with a first end connected to the outlet cone and a second end connected to the inlet cone. The recirculation loop further has an air-circulation device configured to recirculate heated air from the outlet cone to the inlet cone.
