Is Loud Exhausts Legal in Argentina After the 2026 Policy Reforms?

No, loud exhaust systems violate Argentina’s Ley Nacional de Tránsito 24.449 (Art. 65) and Decreto 779/95, which mandate compliance with IRAM 6006 noise emission standards. Local jurisdictions, such as Buenos Aires’ Código de Tránsito y Transporte (Ordenanza 5.227), enforce decibel limits (≤92 dB for motorcycles, ≤90 dB for cars) via municipal inspections. Non-compliance risks fines up to ARS 50,000 and mandatory muffler replacement under Resolución 125/2023 of the Secretaría de Transporte.

Key Regulations for Loud Exhausts in Argentina

  • National Noise Limits: IRAM 6006 caps exhaust noise at 90 dB (cars) and 92 dB (motorcycles), enforced by ANSES and provincial authorities.
  • Local Ordinances: Buenos Aires, Córdoba, and Rosario impose stricter checks via municipal traffic codes, with decibel meters used during roadside inspections.
  • 2026 Compliance Shift: The Ministerio de Transporte plans nationwide OBD-II integration to flag tampered exhausts, aligning with MERCOSUR harmonization efforts.

Enforcement targets modified systems, particularly aftermarket pipes lacking homologation. Vehicles flagged in Sistema Nacional de Licencias de Conducir face mandatory technical reviews. Exemptions exist only for classic cars with original exhausts preserved under Ley 27.136.
