Why does Ducati Devil vent?

There are two reasons why motorcycle exhaust pipes make different noises.

1. The exhaust pipe of motorcycle is easy to be damaged in use, and the damaged exhaust pipe will make abnormal noise, which is very annoying.

2. Fault symptoms: If the vehicle has a broken fire and is not fully burned, it will make a relatively different sound through the exhaust pipe. This sound can be said to be an alarm sound, or it can be said to be a prompt sound from one side of the vehicle. It is not a preset function of the vehicle, but a very normal vehicle fault performance.
