Abstract: An exhaust system for a vehicle is made sufficiently long and yet allows the muffler to be located relatively close to the engine by curving the exhaust pipe about a cooling fan provided for the engine. The arrangement also facilitates mounting of the exhaust system to the engine and vehicle bodies at a fewer number of support points.
