The county sets no vehicle-noise rule of its own. Ann Arbor prohibits any car stereo clearly audible more than 50 feet from the vehicle, and requires a working muffler with no cutouts or bypasses.
Motor-vehicle noise on public roads follows the Michigan Vehicle Code (MCL 257.1+) plus local ordinances. Ann Arbor Chapter 119, Section 9:390, bars operating an electronically amplified sound system in or on a vehicle so as to be clearly audible more than 50 feet away. Section 9:377 requires a muffler in good working order and bans cutouts and bypasses, and Section 9:379 sets dB(A) limits (for example, 82 dB(A) for cars at 35 mph or less). Ypsilanti Township's ordinance similarly bars car stereos plainly audible 50 feet from the source, enforced by the Sheriff.
Ann Arbor vehicle-noise infractions carry fines up to $100; muffler-tampering can be a misdemeanor. Ypsilanti Township treats loud stereos as a misdemeanor up to $500 / 90 days.
