No, loud exhausts are illegal in India under the Motor Vehicles Act, 1988, and Central Motor Vehicles Rules, 1989. Modifying exhaust systems to amplify noise violates Rule 120(2), which mandates compliance with manufacturing standards. State pollution control boards enforce these rules, with recent 2026 directives tightening surveillance on aftermarket modifications.
Key Regulations for Loud Exhausts in India
- Central Motor Vehicles Rules, 1989 (Rule 120(2)): Prohibits alterations to exhaust systems that exceed permissible noise limits (85 dB for two-wheelers, 93 dB for four-wheelers).
- Environment Protection Act, 1986: Empowers State Pollution Control Boards (SPCBs) to penalize vehicles emitting excessive noise, including modified exhausts.
- Motor Vehicles (Amendment) Act, 2019: Introduced stricter penalties (₹10,000–₹50,000) for tampering with noise control devices, effective nationwide from 2026.
Enforcement varies by state; Delhi’s Transport Department and Mumbai’s RTO conduct periodic checks. Courts have upheld confiscation of vehicles with illegal exhausts under Section 190(2) of the MV Act. Aftermarket modifications often lack homologation, rendering them non-compliant with Bharat Stage VI norms.
