No, muffler deletes are illegal in Malaysia under the Road Transport Act 1987 and Land Public Transport Act 2010, as they violate noise emission and vehicle modification standards enforced by the Road Transport Department (JPJ). Modifications altering exhaust systems without approval risk fines up to RM2,000, vehicle confiscation, or prosecution under Section 66 of the Act. The JPJ’s 2026 enforcement push targets non-compliant vehicles, particularly in urban areas.
Key Regulations for Muffler Deletes in Malaysia
- Noise Emission Limits: Vehicles must comply with the Malaysian Standard MS 1000:2016 (max 93 dB for motorcycles, 90 dB for cars), which muffler deletes typically breach.
- JPJ Approval Requirement: Any exhaust modification requires prior certification from JPJ under Rule 10(2) of the Road Traffic Rules 1959; unapproved changes invalidate roadworthiness certificates.
- Type Approval Mandate: Aftermarket parts must bear the SIRIM QAS International mark; muffler deletes lack this certification, rendering them non-compliant.
Enforcement includes roadside checks by JPJ and police, with penalties escalating for repeat offenses. Vehicles flagged for excessive noise face mandatory retesting at authorized centers. The Automotive Development Plan 2026 further tightens scrutiny on non-standard modifications, aligning with ASEAN’s vehicle safety harmonization efforts.
