No, muffler deletes are illegal in Denmark under the Road Traffic Act (Færdselsloven) and Environmental Protection Act (Miljøbeskyttelsesloven). Modifying or removing a vehicle’s exhaust system to increase noise or emissions violates Danish type-approval standards, enforced by the Danish Transport Authority (Trafikstyrelsen) and the Environmental Protection Agency (Miljøstyrelsen). Non-compliance risks fines up to DKK 10,000 (≈€1,340) and mandatory reinstatement of the original system.
Key Regulations for Muffler Deletes in Denmark
- Type-approval compliance: Vehicles must adhere to EU Regulation 540/2014, which mandates noise limits (74 dB for passenger cars) and emissions standards. Deviations invalidate roadworthiness certificates.
- Environmental Protection Act: Exhaust modifications that exceed noise or pollution thresholds are prohibited, with enforcement by municipal authorities and police.
- 2026 EU Real-Driving Emissions (RDE) alignment: Denmark’s pending transposition of stricter RDE tests (via EU 2023/443) will further penalize non-compliant exhaust systems, including muffler deletes, during periodic technical inspections (syn).
Enforcement prioritizes roadside checks and data-sharing between Trafikstyrelsen and customs agencies. Imported vehicles with pre-modified exhausts must undergo retroactive certification or face confiscation.
