What is claimed is: 1. An exhaust system for a snowmobile, the snowmobile comprising a forward portion in which an engine is mounted, a rearward portion, and a track belt for propelling the snowmobile, the exhaust system comprising: an exhaust pipe extending above the track belt from the engine to the rearward portion of the snowmobile, the exhaust pipe including a tail pipe having an outlet to the atmosphere; wherein the rearward portion of the snowmobile includes a space defined between a first lateral wall, a second lateral wall, and a rear wall, the space having an opening facing the track belt, the tail pipe being located in the space; and wherein the tail pipe is configured to discharge exhaust gas onto the track belt. 2. The exhaust system of claim 1, wherein the snowmobile includes a frame located in the rearward portion and being configured to substantially cover the track belt, the frame comprising at least one of the first lateral wall, the second lateral wall, and the rear wall and at least partially defining the opening of the space, the snowmobile further comprising a cover member coupled with the frame and configured to cover the opening from above. 3. The exhaust system of claim 2, further comprising a muffler coupled with the exhaust pipe and at least partially surrounded by the cover member. 4. The exhaust system of claim 3, wherein the snowmobile further comprises a load-carrying platform located behind the space. 5. The exhaust system of claim 2, wherein the snowmobile further comprises a load-carrying platform located behind the space. 6. An exhaust system for a snowmobile, the snowmobile comprising a forward portion in which an engine is mounted, a rearward portion, and a track belt for propelling the snowmobile, the exhaust system comprising: an exhaust pipe extending above the track belt from the engine to the rearward portion of the snowmobile, the exhaust pipe including a tail pipe having an outlet to the atmosphere; wherein the rearward portion of the snowmobile includes a space defined between a first lateral wall, a second lateral wall, and a rear wall, the space having an opening facing the track belt, the tail pipe being located in the space; and wherein the tail pipe comprises a downstream end and an upstream end located between the downstream end and the exhaust pipe, wherein the tail pipe is configured such that when the exhaust system is mounted to the snowmobile, the outlet of the tail pipe is located at an elevation below the upstream end of the tail pipe and faces toward the forward portion of the snowmobile. 7. The exhaust system of claim 6, further comprising a guard plate coupled with the rearward portion of the snowmobile, the guard plate configured to covers at least a lower portion of the tail pipe. 8. The exhaust system of claim 7, wherein the snowmobile further comprises a load-carrying platform located behind the space. 9. The exhaust system of claim 6, wherein the snowmobile further comprises a load-carrying platform located behind the space. 10. The exhaust system of claim 1, wherein the snowmobile further comprises a load-carrying platform located behind the space. 11. The exhaust system of claim 1, wherein the tail pipe comprises a downstream end and an upstream end located between the downstream end and the exhaust pipe, wherein the tail pipe is configured such that when the exhaust system is mounted to the snowmobile, the outlet of the tail pipe is located at an elevation below the upstream end of the tail pipe and faces toward the forward portion of the snowmobile. 12. The exhaust system of claim 11, further comprising a guard plate coupled with the rearward portion of the snowmobile, the guard plate configured to covers at least a lower portion of the tail pipe. 13. The exhaust system of claim 12, wherein the snowmobile further comprises a load-carrying platform located behind the space. 14. The exhaust system of claim 11, wherein the snowmobile further comprises a load-carrying platform located behind the space. 15. A snowmobile, comprising: a frame having a forward portion and a rearward portion; an engine mounted in the forward portion of the frame; a track belt for propelling the snowmobile coupled with the rearward portion of the frame; an exhaust pipe extending above the track belt and behind the engine, the exhaust pipe including a rear portion having an outlet to the atmosphere; and a cavity at least partially defined by the frame and comprising a rear wall and an opening that faces the track belt; wherein the rear portion of the exhaust pipe extend through the cavity and the outlet is forward of the rear wall. 16. The snowmobile of claim 15, wherein the frame comprises a first lateral wall, a second lateral wall, the first and second later walls and the rear wall and at least partially defining the opening of the cavity. 17. The snowmobile of claim 16, further comprising a cover member coupled with the frame and configured to cover the opening of the cavity from above. 18. The snowmobile of claim 17, further comprising a muffler coupled with the exhaust pipe and located between the cover member and the opening of the cavity. 19. The snowmobile of claim 15, further comprises a load-carrying platform located behind the cavity. 20.
