No, muffler deletes are illegal in Indonesia under national emissions and vehicle modification laws enforced by the Ministry of Transportation (MoT) and the National Police. Modifying or removing a vehicle’s exhaust system violates mandatory noise and emissions standards, risking fines, impoundment, or criminal charges under Law No. 22/2009 on Traffic and Road Transport.
Key Regulations for Muffler Deletes in Indonesia
- Ministry of Transportation Regulation No. 5/2020 mandates that all motor vehicles must comply with Euro 4 emissions standards, requiring intact exhaust systems. Deviations, including muffler removal, are explicitly prohibited.
- National Police Circular No. 6/2021 empowers traffic officers to issue administrative penalties (e.g., vehicle confiscation) for non-compliant modifications, including muffler deletes, under traffic safety protocols.
- Regional Ordinances (e.g., DKI Jakarta Perda No. 8/2022) impose localized enforcement, with municipal authorities conducting periodic roadside checks to detect illegal modifications, particularly in urban areas.
Enforcement has intensified ahead of Indonesia’s 2026 ASEAN haze reduction commitments, with inter-agency task forces (MoT, National Police, and Ministry of Environment) prioritizing non-compliant vehicles. Violators face administrative sanctions (e.g., mandatory reinstallation) or criminal liability under the Environmental Law No. 11/2020 for contributing to air pollution. Aftermarket parts must bear SNI (Indonesian National Standard) certification; uncertified mufflers or deletes are inadmissible.
