Glitch: Silence: Whip off track:
Use the following trick to get whipped off of the Silence track in the Jack division. Get a light, quick vehicle and go as fast as possible. When you reach the energy strips, drive on the ones to the right and make sure that you are going at least 1200 km/h. When you get to the end of the strip, you will mysteriously fall off the track onto the ground below.
