Post-processing system

A post-processing system comprising:

• a first processing section that extends in a direction of a first cylinder axis and processes exhaust discharged from an internal combustion engine, the first processing section having a cylindrical shape;
• and
• a second processing section that is disposed on an exhaust downstream side compared to the first processing section, extends in a direction of a second cylinder axis, and processes the exhaust, the second processing section having a cylindrical shape,
• wherein the post-processing system further comprises:
• a first pipe that extends in a direction at a first angle with respect to the direction of the first cylinder axis, is disposed on the first processing section to be rotatable around the first cylinder axis, and guides out the exhaust processed by the first processing section,
• a second pipe that extends in a direction at a second angle with respect to the direction of the second cylinder axis, is disposed on the second processing section to be rotatable around the second cylinder axis, and introduces the exhaust processed by the second processing section, and
• a third pipe that is formed to have an angle obtained by adding the first angle and the second angle and couples the first pipe with the second pipe.
