No, Maine’s noise ordinances and vehicle equipment laws prohibit exhaust systems modified to amplify sound, with enforcement by the Bureau of Motor Vehicles and local law enforcement. Violations may result in fines up to $500 or vehicle impoundment under 29-A MRSA §1917.
Key Regulations for Loud Exhausts in Maine
- Noise Limits: Exhaust noise exceeding 92 decibels (measured at 50 feet) violates state law, per 10-144 CMR ch. 101, aligning with EPA standards.
- Equipment Standards: 29-A MRSA §1712 mandates that exhaust systems must prevent excessive noise or smoke, with aftermarket modifications scrutinized for compliance.
- Local Enforcement: Municipalities like Portland and Bangor enforce additional noise ordinances, often targeting vehicles with “straight pipes” or resonator deletions.
Recent 2026 compliance shifts include stricter decibel testing protocols at inspection stations, driven by federal highway safety grants. Courts have upheld impoundments for repeat offenders, citing public nuisance concerns.
