Abstract
An exhaust system for an internal combustion engine includes an enclosure with a top wall having an opening. An exhaust pipe includes an exhaust outlet and an outlet flange which is attached to the pipe at the exhaust outlet. The outlet flange is disposed adjacent to the opening in the enclosure. An exhaust muffler includes an exhaust inlet and an inlet flange which is attached to the muffler at the exhaust inlet. A rain skirt is interposed between and attached to each of the outlet flange of the exhaust pipe and the inlet flange of the exhaust muffler. The rain skirt has a hole therein allowing fluid communication between the exhaust pipe and the exhaust muffler. The rain skirt extends outwardly from the outlet flange and prevents water from entering into the enclosure through the opening.
