(A) Every motor vehicle shall at all times be equipped with a muffler in good working order and in constant operation to prevent excessive or unusual noise. No person shall use a muffler cutout, bypass, or similar device upon a motor vehicle on a highway. No person shall modify the exhaust system of a motor vehicle in any manner which will amplify or increase the noise or sound emitted louder than that emitted by the muffler originally installed on the vehicle.
(B) No person shall be permitted to operate or allow to be operated on an internal combustion engine powered vehicle on any posted public ways, including, but not limited to, streets, alleys, easements, or right-of-ways established for vehicle operation within the city while the vehicle or operator is utilizing an engine brake or Jake brake without an exhaust muffler sufficient to prevent the creation of excessively loud noises by the vehicle, except when the use of the engine or Jake brake is necessary for the safe operation of the vehicle. This section is not intended to prohibit the passage of vehicles equipped with engine or Jake brakes in posted areas, but rather limit the use of the equipment in posted areas under the aforesaid circumstances.
