Abstract
An improved muffler system for mounting within a restricted engine compartment such as the engine compartment of a small off-road vehicle including a muffler surrounded by a heat shield having a plurality of apertures formed therein for selectively cooling selected certain areas of the engine compartment in conjunction with a venturi which creates a flow of cooling air from outside the engine compartment, over the engine, into the apertures, between the heat shield and the muffler to a point where the exhaust gas and the initially cooler air are mixed and subsequently exited into the atmosphere.
