Summary

316.272 Exhaust systems, prevention of noise. — (1) Every motor vehicle shall at all times be equipped with an exhaust system in good working order and in constant operation, including muffler, manifold pipe, and tailpiping to prevent excessive or unusual noise. In no event shall an exhaust system allow noise at a level which exceeds a maximum decibel level to be established by regulation of the Department of Environmental Protection as provided in s. 403.061 (11) in cooperation with the Department of Highway Safety and Motor Vehicles. No person shall use a muffler cutout, bypass or similar device upon a vehicle on a highway.
(2) The engine and power mechanism of every motor vehicle shall be so equipped and adjusted as to prevent the escape of excessive fumes or smoke.
(3) A violation of this section is a noncriminal traffic infraction, punishable as a nonmoving violation as provided in chapter 318.
Full Breakdown
FL Statute 316.272 requires all motor vehicles to have a functioning muffler and prohibits excessive or unusual noise, plus cutouts, bypasses, or similar devices. FL 316.3045 (plainly audible car stereo at 25 feet) was reinstated after the 2022 Florida Supreme Court ruling upheld the law. St. Petersburg Police actively enforce both statutes, particularly along Central Avenue, 4th Street North, and the Pinellas Bayway approaches during weekend evenings. City Code Chapter 11 provides additional local tools for chronic offenders. Motorcycle noise is a recurring complaint around the Historic Old Northeast and downtown residential corridors.
Violations & Fines
State moving violation fine typically 114 dollars. City civil citations possible for repeat or egregious modifications. Exhaust system alteration can void vehicle inspection in the rare case where one is required (FL does not have general inspections).
