Abstract: An exhaust pipe structure includes an exhaust pipe, a branching portion including an inflow port, a first flow path, a second flow path, a first discharge port, and a second discharge port, a first muffler, a first pipe, a second muffler, and a second pipe. The second flow path is lower in position in an up-down direction of a vehicle than the first flow path at a downstream side part of the second flow path including at least a portion of the second discharge port. The second pipe is lower in position in the up-down direction of the vehicle at an upstream side part connected to the second discharge port than an upstream side part of the first pipe connected to the first discharge port.
