extremly quiet when cruising around . however when you mash the pedal, it gets loud but has an awesome sound.
i've had it for 3 years now, and i've had many cops following me. never got pulled over for it being loud!!!
though i believe they discontinued this model recently. george from raptor racing said this to one of my friends 2-3 weeks ago.
they will have a new model out for the mk3 though
