Answer options: ✅ It must not exceed the noise level produced by the original exhaust system or be 'unnecessary noise'.

  • 100 decibels at idle.
  • 92 decibels at 30 metres.
  • There is no specific decibel limit, only a visual inspection for modifications.

Correct answer: It must not exceed the noise level produced by the original exhaust system or be 'unnecessary noise'.

Explanation: Ontario regulations generally state that a motorcycle's exhaust system must not be modified to produce a louder sound than the original manufacturing equipment and must not create 'unnecessary noise'. Specific decibel limits can vary and are often tied to subjective enforcement through 'unnecessary noise' clauses.
