No, Belgium prohibits exhaust systems emitting excessive noise under the Code de la route (Road Traffic Code), enforced by regional authorities. Modified exhausts exceeding 92 dB(A) during stationary tests or 95 dB(A) while driving violate Article 8.12. Local police and FOD Mobiliteit conduct roadside checks, with fines up to €1,600 for non-compliance. From 2026, stricter EU-wide noise limits may further tighten enforcement.
Key Regulations for Loud Exhausts in Belgium
- Decibel Limits: Stationary tests cap exhaust noise at 92 dB(A); driving tests at 95 dB(A). Exceeding these triggers penalties under Arrêté royal du 1er décembre 1975.
- Type Approval: Aftermarket exhausts must hold ECE R59-02 certification. Unapproved systems are illegal, even if “silent” in design.
- Regional Enforcement: Flanders (Vlaamse Milieumaatschappij) and Wallonia (SPW Environnement) conduct targeted campaigns, while Brussels applies Ordonnance bruits de voisinage for nuisance complaints.
Non-compliant vehicles face immediate confiscation of the exhaust system and administrative immobilization. Dealers importing modified exhausts must verify compliance with Directive 2007/46/EG.
