Hi wce and Tyler,
I heard one in 88 and it sounded just as noisy to me as a casual observer across the street.
I did find my yellow Vortex slightly quieter after a direct comparo with another Powertorque but that could be down to the individual engines rather than all the covering.
By looking at it, you'd think it would be whisper quiet.
But not going to happen with a 2 stroke.
I think any noise reduction worth noting is down to the lower typical operating revs required due to the lift effect of the Vortex cutting disc.
