The sound limit is mandatory.  Bring more than enough sound reduction equipment and work your way from quiet to just passing, remember you only get one sound failure, a second sound failure ends your day.  Airbox, long silencer or two, and 90 degree bends in the connecting pipe and a 90 degree bend on the output of the silencer with the output facing drivers left and down.  Experts to consult are Ian Harrison of Viper Racing, UK for Superkarts, and Art Verlinger of RLV for the rest of the karts.
