Ohio law requires every motor vehicle to have a working muffler and bans removing or disabling it. Dayton adds an 80 dB(A) motor-vehicle limit measured at 15 feet and bars amplified vehicle sound audible 25 feet away.
Vehicle noise is governed by state law plus local codes; there is no separate county rule. Ohio Revised Code 4513.221 lets counties and townships require a factory or equivalent muffler in good working order and prohibit removing, disabling, or racing an engine to produce unusual exhaust noise. Dayton's code caps motor-vehicle noise at 80 dB(A) measured at least 15 feet from the source, bars defective or modified exhaust and rapid acceleration or tire squealing, and prohibits vehicle sound systems discernible 25 feet or more away. These rules apply throughout the county through state law and each city's ordinance.
Ohio muffler violations are minor misdemeanors. In Dayton, excessive vehicle sound-system noise (§ 94.12) starts as a minor misdemeanor, escalating to fourth- and third-degree misdemeanors on repeat offenses.
