No, muffler deletes are illegal in Belgium under the Royal Decree of 15 March 1968 on road traffic regulations, which mandates vehicles must maintain original or equivalent exhaust systems to meet EU noise and emissions standards. Modifications voiding homologation risk fines up to €1,376 and vehicle impoundment. The 2026 EU Euro 7 standards further tighten compliance, requiring certified aftermarket parts.
Key Regulations for Muffler Deletes in Belgium
- Homologation Requirement: Any exhaust modification must retain the original noise level (≤ 74 dB for cars) and emissions compliance, verified by a certificat de conformité issued by the manufacturer or a recognized body like SPW Mobilité (Wallonia) or Flanders’ Agentschap Wegen en Verkeer.
- Penalties for Non-Compliance: Police or customs (Douane) can issue procès-verbaux for uncertified modifications, leading to administrative immobilization. Repeat offenses escalate to criminal liability under the Code de la route (Art. 8.17).
- 2026 EU Euro 7 Transition: From July 2026, all new vehicles must meet stricter limits. Retrofitted systems must pass Rijksdienst voor het Wegverkeer (RVW) testing, with muffler deletes explicitly excluded unless pre-approved under Annex II of Regulation (EU) 2018/858.
