Abstract
The invention relates to an engine with an exhaust gas pathway extending between the engine and the atmosphere. The engine includes a manifold portion fluidically connected to an engine, a muffler portion fluidically connected to the atmosphere, a conduit portion fluidically connected between the manifold portion and the muffler portion, and a plurality of baffles operationally connected within the muffler. A substantially fibrous refractory material at least partially coats the exhaust gas pathway. Exhaust gas from the engine flowing through the exhaust gas pathway to the atmosphere flows over the substantially fibrous refractory material.
