October 20, 2006 - In an effort to control sound at the BooKoo Arenacross Championship Series, sound requirements will be implemented throughout the series in all classes.

All motorcycles must no exceed 99 db on the “A” scale at 20 inches.  

Typically stock motorcycles have no problem in meeting these requirements which are being implemented by several race tracks and sanction organizations throughout the country. In addition, the majority of the exhaust manufactures now have changeable cones with a variety of outlets ranging from 2”-1.5” to allow a variety of adjustments to meet these requirements.
