Abstract
A utility vehicle includes an exhaust assembly fluidly coupled to an engine. Depending on various parameters, such as the size and/or performance of the vehicle, the exhaust assembly is required to meet certain emissions regulations. Such emissions regulations may be met by increasing the temperature within the exhaust assembly, however, at particularly high temperatures, a catalyst of the exhaust assembly may be damaged. Therefore, the exhaust assembly includes various options for cooling portions thereof to remove heat from the assembly.
