Snowmobile exhaust system

摘要

A snowmobile has a frame including a tunnel, a least one ski operatively connected to the frame, a seat disposed above the tunnel, a fuel tank disposed on the frame, and an engine connected to the frame forwardly of the fuel tank. The engine has at least one cylinder, at least one intake port, at least one exhaust port, and a laterally extending output shaft defining an output shaft axis. An endless track is disposed at least in part under the tunnel and is operatively connected to the engine. An air intake system is fluidly connected to the at least one intake port. An exhaust system is fluidly connected to the at least one exhaust port. The exhaust system includes a muffler disposed between the output shaft axis and the fuel tank in a longitudinal direction of the snowmobile.
