Summary
Lexington County bans loud, unnecessary vehicle noise that disturbs a residential area, and it specifically tells courts to weigh whether a car or motorboat carries a factory-level muffler when deciding a case. Section 26-32 covers the ban; violating it is a misdemeanor enforced by the sheriff's deputies.
(a)It shall be unlawful for any person within the unincorporated areas of the county to willfully make or continue, or cause to be made or continued, any loud, unnecessary and unusual noise which disturbs the peace and quiet of any unincorporated or incorporated residential area or which causes discomfort or annoyance to any person in any unincorporated or incorporated residential area of the county. This noise shall include, but not be limited to, noises made by motor vehicles, motorboats, mechanical devices, electrical devices, electronic devices, human voice, music, musical instruments, animals, and all activities accessory to residential living. ... (6)In the case of motor vehicles and/or motorboats, whether or not such vehicles are equipped with mufflers and/or such suppression devices which keep exhaust noises down to a level equal to or below that which the manufacturers of such vehicles provided as original equipment designed for acceptable use.

Full Breakdown
Section 26-32(a) of the county's noise article sets a general standard before it gets specific about vehicles: it's 'unlawful for any person within the unincorporated areas of the county to willfully make or continue, or cause to be made or continued, any loud, unnecessary and unusual noise which disturbs the peace and quiet of any unincorporated or incorporated residential area or which causes discomfort or annoyance to any person' there, and the statute expressly lists 'noises made by motor vehicles' among the covered sources alongside motorboats, mechanical and electronic devices, and music.
Rather than setting a decibel limit, the ordinance tells whoever is deciding a case, a magistrate or enforcement officer, what to weigh. ' In practice that means a car or truck running a straight-pipe or otherwise modified exhaust louder than its factory muffler is the kind of vehicle noise the section targets, evaluated alongside the other listed factors, such as the noise's intensity, the neighborhood's character, the time of day, and whether law enforcement or citizens have complained about it before. '
Violations & Fines
A Section 26-32(a) violation, including excessive exhaust or engine noise from a car or motorboat lacking factory-level muffling, is a misdemeanor under Section 26-34(a), fined up to the maximum the magistrate's court can impose. Lexington County sheriff's deputies enforce the noise article under Section 26-33. Fireworks noise is carried separately under Section 26-32(b) as a civil infraction with a flat $150 fine, not the vehicle-noise misdemeanor track.
