As many of you know there are strict, zero tolerance noise limits at this track. While most classes are compliant, shifters (particularly Hondas) can be a problem.
Our suggestion is to use an air box and fit the longest silencer available to you. As this is a track specific regulation, it is imperative you comply. Track personnel will be monitoring compliance and CAN-AM Karting Challenge staff will have decibel meters on-hand to help police the situation.
