The exhaust must record a decibel level of or below 101 db(A).

This level will be recorded at the level of the exhaust or 200mm from ground level which ever is greater, placed 500mm away from the exhaust outlet at a 45 degree angle to said outlet.

The engine will be run at a speed between two thirds and three quarters of it’s maximum to achieve the recording.
