Chapter 90 Section 16 Offensive or illegal operation of motor vehicles. This statute states (in part):

"No person shall operate a motor vehicle, nor shall any owner of such vehicle permit it to be operated upon any way, except fire department and fire patrol apparatus, unless such motor vehicle is equipped with a muffler to prevent excessive or unnecessary noise, which muffler is in good working order and in constant operation, and complies with such minimum standards for construction and performance as the registrar may prescribe. No person shall use a muffler cut-out or by-pass. No person shall operate a motor vehicle on any way which motor vehicle is equipped (1) with a muffler from which the baffle plates, screens or other original internal parts have been removed and not replaced; or (2) with an exhaust system which has been modified in a manner which will amplify or increase the noise emitted by the exhaust."

This is the same section of law that prohibits the use of a siren or lights unless you are emergency vehicle, and prohibits the use of studded tires between May 1st and November 1st.

It also sets forth the fine as described below:

"Whoever violates the provisions of this paragraph shall be punished by a fine of not more than fifty dollars."
