"Guide to Modified Exhaust Systems: A Reference for Law Enforcement Officers and Motor Vehicle Inspectors" is a slim, portable manual that concisely provides law enforcement personnel and regular citizens the tools they need to fight back against excessive vehicle noise levels. The book includes numerous color photographs to make it easy to visually identify the illegal equipment installed on some motorcycles that is responsible for the great majority of nuisance noise levels.
Excessive noise is a major public health issue. High noise levels are associated with hearing loss, heart disease, sleep deprivation, chronic fatigue, ringing of the ears, and aggressive behavior. Loud noise also damages communities, reduces property values, and denies individuals the right to peacefully enjoy their own home and property.
