3. The exhaust assembly of claim 1 , wherein the third height is greater than the fourth and fifth heights.

4. The exhaust assembly of claim 1 , wherein the fourth and fifth heights are substantially equal.

5. The exhaust assembly of claim 1 , wherein the first muffler is laterally centered with respect to the vehicle.

6. The exhaust assembly of claim 5 , wherein the first and second exhaust devices are disposed laterally outboard of the first muffler and on opposing lateral sides of the first muffler.

7. The exhaust assembly of claim 6 , wherein the second muffler is disposed laterally between the first exhaust device and the first muffler, and the third muffler is disposed laterally between the second exhaust device and the first muffler.

8. The exhaust assembly of claim 1 , wherein the second muffler further includes a fifth outlet fluidly connected to the third inlet and the third outlet, and the third muffler further includes a sixth outlet fluidly connected to the fourth inlet and the fourth outlet.

9. The exhaust assembly of claim 8 , further comprising a first exhaust outlet pipe adapted to receive exhaust gas from the third outlet, a second exhaust outlet pipe adapted to receive exhaust gas from the fifth outlet, a third exhaust outlet pipe adapted to receive exhaust gas from the fourth outlet, and a fourth exhaust outlet pipe adapted to receive exhaust gas form the sixth outlet, each of the first, second, third, and fourth exhaust outlet pipes opening toward a rear of the vehicle.

10. The exhaust assembly of claim 9 , wherein the first, second, third, and fourth exhaust outlet pipes include respective seventh, eighth, ninth, and tenth outlets that are disposed at a sixth height with respect to the surface.

11. The exhaust assembly of claim 9 , wherein one of the first and second exhaust outlet pipes includes a first E-valve and one of the third and fourth exhaust outlet pipes includes a second E-valve.

12. The exhaust assembly of claim 1 , wherein the first exhaust device is a first gasoline particulate filter (GPF) and the second exhaust device is a second GPF.

13. The exhaust assembly of claim 1 , wherein the first housing has a first dimension perpendicular to the surface and a second dimension parallel to a longitudinal axis of the vehicle, the first dimension being greater than the second dimension.

14. The exhaust assembly of claim 1 , wherein each of the second and third housings defines a first dimension perpendicular to the surface and a second dimension parallel to a longitudinal axis of the vehicle, the second dimension being greater than the first dimension.

15. An exhaust assembly for receiving exhaust gas from an engine of a vehicle adapted to travel along a surface, the exhaust assembly comprising:

a first exhaust device adapted to receive exhaust gas from the engine;

a second exhaust device adapted to receive exhaust gas from the engine;

a first muffler including an X-pipe having a first inlet adapted to receive exhaust gas from the first exhaust device, a second inlet adapted to receive exhaust gas from the second exhaust device, a first outlet, and a second outlet, the first and second inlets and the first and second outlets being fluidly connected to one another;

a second muffler including a second housing, a third inlet in direct receipt of exhaust gas from the first outlet, and a third outlet; and

a third muffler including a third housing, a fourth inlet in direct receipt of exhaust gas from the second outlet, and a fourth outlet, wherein the first and second exhaust devices are disposed laterally outboard of the first muffler and on opposing sides of the first muffler.

16. The exhaust assembly of claim 15 , wherein the first muffler is laterally centered with respect to the vehicle.

17. The exhaust assembly of claim 15 , wherein the first exhaust device is disposed laterally between the first muffler and the second muffler, and the second exhaust device is disposed laterally between the first muffler and the third muffler.
