No, West Virginia prohibits exhaust systems that produce excessive noise under W. Va. Code § 17C-15-27, aligning with federal noise standards enforced by the West Virginia Division of Motor Vehicles (DMV). Modified exhausts exceeding 92 decibels (dB) during stationary testing or 88 dB while operating are unlawful, with local law enforcement empowered to issue citations under WV Code § 17C-15-28.
Key Regulations for Loud Exhausts in West Virginia
- Decibel Limits: Exhaust noise must not exceed 92 dB when measured at 50 feet from the vehicle’s path under WV DMV’s 2024 enforcement guidelines, with 88 dB enforced during stationary inspections.
- Local Enforcement: Municipalities like Charleston and Morgantown may impose additional noise ordinances stricter than state law, requiring compliance with municipal codes (e.g., Charleston Municipal Code § 117-12).
- Modification Restrictions: Aftermarket exhaust systems must retain original manufacturer specifications; any alteration that amplifies noise beyond legal thresholds violates W. Va. Code § 17C-15-27(3).
Violations incur fines up to $100 for first offenses, escalating to $200 for repeat infractions under WV Code § 17C-15-29. The West Virginia State Police’s 2026 traffic safety initiative targets modified exhausts, mandating decibel testing during routine stops. Dealers and repair shops face liability for installing non-compliant systems under WV Code § 17C-15-30.
