No. Muffler deletes violate China’s Vehicle Emission Standards (GB 18352.6-2016) and require MIIT type approval, which aftermarket modifications rarely obtain. Local enforcement by the Ministry of Ecology and Environment (MEE) and public security traffic authorities has intensified, with 2026 revisions tightening penalties for non-compliant exhaust systems.
Key Regulations for Muffler Deletes in China
- GB 18352.6-2016 Compliance: Vehicles must meet China’s emission limits, which aftermarket muffler deletes typically fail due to altered backpressure and catalytic converter removal.
- MIIT Type Approval: Any exhaust modification requires certification from the Ministry of Industry and Information Technology; unapproved systems risk vehicle registration revocation.
- MEE Enforcement: The Ministry of Ecology and Environment conducts roadside inspections and remote sensing monitoring, with fines up to ¥50,000 for violations under the Air Pollution Prevention and Control Law.
Local traffic police may impound vehicles with illegal modifications, and insurers often deny claims for non-compliant exhaust systems. Aftermarket suppliers face liability under the Product Quality Law if modifications cause emissions exceedances.
