Abstract: An exhaust system for an off-road vehicle including an outlet port configured to release exhaust gas and an outlet stack disposed about the outlet port, in which at least a portion of the outlet stack is radially spaced from the outlet port to form a gap between the outlet stack and the outlet port. The outlet stack is configured to direct a flow of exhaust gas from the outlet port toward a distal end of the outlet stack. The exhaust system further includes an exhaust shield in close proximity or coupled to the outlet stack comprising at least one opening and an electronic control unit (ECU) disposed within the exhaust shield. The gap is configured to establish an airflow path from the at least one opening to a region of the outlet stack downstream from the outlet port, and the ECU is positioned within the airflow path between the at least one opening and the gap to facilitate cooling of the ECU.
