A snowmobile has a frame including a tunnel having a passage therethrough, at least one ski, an engine having an engine air inlet and an engine exhaust outlet, and a drive track operatively connected thereto and disposed at least partly below the tunnel around a rear suspension. A heat exchanger connected to the tunnel has heat exchanger engine air inlet and outlet, a cooling air inlet and a cooling air outlet fluidly connected between the cooling air inlet and the passage. A snowmobile has a pipe fluidly connected to the exhaust outlet and having first and second pipe outlets. The snowmobile further has a muffler having first and second muffler inlets and a muffler outlet, a turbocharger, first and second exhaust flow passages, and a valve disposed between the pipe and the first muffler inlet for selectively controlling the flow of exhaust gas flowing through the first exhaust flow path.
