Is Muffler Deletes Legal in Chile After the 2026 Law Changes?

No. Muffler deletes are illegal in Chile under environmental and traffic regulations enforced by the Superintendencia del Medio Ambiente (SMA) and Ministerio de Transportes y Telecomunicaciones (MTT). Modifying or removing mufflers violates Decree 10/2017, which mandates compliance with Euro 5 emission standards for vehicles, and Decree 122/2017 for noise limits. Non-compliance risks fines up to 1,000 UTM (~$85,000 USD) and vehicle impoundment.

Key Regulations for Muffler Deletes in Chile

  • Decreto Supremo 10/2017: Requires all vehicles to meet Euro 5 emission standards; muffler deletes invalidate type-approval certificates.
  • Decreto Supremo 122/2017: Sets maximum noise levels at 93 dB(A) for light vehicles; modified exhausts often exceed this threshold.
  • Ley 20.418 (2010): Empowers the SMA to inspect vehicles and impose penalties for non-compliance with environmental norms.

The MTT’s 2026 enforcement plan prioritizes roadside inspections targeting modified exhaust systems, with AI-driven detection systems in Santiago and Valparaíso. Imported vehicles must also comply with these standards upon registration. Exemptions are rare, typically limited to historic or racing vehicles with special permits.
