Check the new video of a true VOE GTO running the new generation VOE mufflers. Turn the sound up and you can hear the valves switching. You can hear the Humbler rumble when they are in the loud mode.
It is hard for the camera microphone to relay the 10 dBA sound differential but it is there.
Awesome cars these are!
