Exhaust system for an off-road vehicle

An exhaust system for an off-road vehicle comprising:

• a housing comprising a body and an outlet port extending upwardly from the body, wherein the body extends radially outward beyond the outlet port, and the outlet port is configured to release exhaust gas;
• an exhaust shield disposed about the body, wherein the exhaust shield comprises at least one opening configured to enable cooling air to flow from outside the off-road vehicle directly into the exhaust system;
• an electronic control unit (ECU) disposed within the exhaust shield;
• and
• an outlet stack disposed about the outlet port such that 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, wherein the outlet stack is configured to:
• receive the exhaust gas from the outlet port to establish a low pressure region in the outlet stack that aspirates the cooling air through the at least one opening, over the ECU, and into the outlet stack;
• and
• direct flow of the exhaust gas and the cooling air toward a distal end of the outlet stack.
