No, New Jersey prohibits exhaust systems producing excessive noise under N.J.S.A. 39:3-71, with enforcement by the Motor Vehicle Commission and local police. Violations carry fines up to $250 for first offenses, escalating with repeat infractions. Local ordinances, such as Newark’s 2023 noise ordinance, further restrict modifications.
Key Regulations for Loud Exhausts in New Jersey
- Decibel Limits: Exhaust noise exceeding 92 dB(A) at 50 feet violates state standards, per N.J.A.C. 13:1G-3.1. Municipalities may impose stricter limits.
- Modification Bans: Aftermarket exhaust systems must retain original manufacturer-approved noise levels; unauthorized alterations are illegal.
- Enforcement Shifts: Since 2024, the MVC’s “Operation Silent Ride” targets modified vehicles, requiring compliance checks during inspections.
Local agencies like the NJDEP’s Office of Noise Control collaborate with police to address complaints. Courts may mandate exhaust system replacements for violations. Owners should verify compliance before modifications, as 2026 state budget proposals include increased penalties for repeat offenders.
