LOOK: The Davao City government is eyeing the implementation of a stricter muffler regulation ordinance by June, aiming to balance motorists’ preferences with public safety and noise control.

The measure, pushed for second reading at the City Council, allows the use of modified or aftermarket mufflers, provided they comply with Land Transportation Office (LTO) standards, particularly the maximum noise limit of 99 decibels.

However, illegal mufflers such as “kalkal,” “bora-bora,” open pipe, drag pipe, and other non-compliant modifications remain prohibited.

Under the proposed penalties, violators face a ₱2,500 fine for motorcycles on the first offense, along with confiscation of the muffler and vehicle impoundment until compliance. Other motor vehicles face a higher ₱5,000 fine for the first offense. Establishments or shops may be fined ₱5,000 and risk revocation of business permits or legal action if operating without permits.

The ordinance covers not only motorcycles and scooters but also tricycles, passenger cars, public utility vehicles such as jeepneys, taxis, UV Express, buses, and even light and heavy trucks operating in the city.

City officials said the measure was refined following public consultations, where riders and concerned citizens expressed support for clearer, fairer guidelines in regulating modified mufflers.

The ordinance, approved in March, is now awaiting the mayor’s signature, with authorities set to procure decibel meters to ensure proper and consistent enforcement.
