In an exhaust system for an internal combustion engine, an exhaust pipe is reliably bent and deformed during vehicle rear collision while improving drainage performance in the exhaust pipe in normal times. The exhaust system 1 includes a second pipe 17 corresponding to a downstream end part of an exhaust pipe 10 through which exhaust gas flows from an engine 2. The second pipe 17 includes: a fragile part 30 as a starting point of bending deformation of a tail pipe 13; and a partition plate 20 vertically dividing the inside of the second pipe 17 to form, under the partition plate 20, a lower passage 7 to flow water that accumulates in the exhaust pipe 10. The partition plate 20 is in a vicinity of the fragile part 30 and at a position not overlapping with the fragile part 30 in an axial direction of the second pipe 17.
