The county has no vehicle-noise ordinance. Killeen requires exhaust to pass through a muffler that prevents loud noises and bars vehicles so out of repair they grate or rattle; Temple requires working mufflers and prohibits cut-outs.
Vehicle-noise rules come from the cities plus statewide law. Killeen prohibits discharging engine exhaust into the open air except through a muffler that prevents loud or explosive noise, and bars any vehicle 'so out of repair or so loaded' that it creates loud grating, grinding or rattling noise. Temple requires every vehicle to have an efficient, working muffler, prohibits cut-outs, and bars unnecessary horn use and rattling loads. Texas Transportation Code muffler rules apply statewide, including unincorporated Bell County. There is no county 'jake brake' or engine-noise ordinance; loud motor-vehicle noise on public roads outside cities is chiefly a state traffic-code and disorderly-conduct matter.
Killeen: misdemeanor, $100-$2,000. Temple: municipal citation for muffler/noise violations. Statewide muffler defects are a traffic offense; disorderly-conduct noise is Class C.
