Modified exhaust, excessive engine revving, car stereos audible beyond 25 feet, and squealing tires are prohibited under Cornelius Code and N.C.G.S. 20-128 (muffler requirement). I-77 corridor noise from commercial vehicles is regulated through state law.
N.C.G.S. 20-128 requires every motor vehicle to have a properly functioning muffler and prohibits any modification that amplifies exhaust sound beyond factory levels; cutouts, straight-pipes, and bypass valves are specifically illegal. N.C.G.S. 20-128.1 bans exhaust systems emitting visible smoke. Cornelius Code Ch. 52 adds the 25-foot audible-stereo rule common across NC towns. Engine-brake (Jake Brake) use by commercial trucks on I-77 through-town is discouraged by posted 'No Engine Braking' signage, though NCDOT controls the interstate itself. The Exit 28 and Exit 30 ramps see frequent enforcement by Cornelius PD and NC Highway Patrol. Motorcycle exhaust meeting EPA label requirements is compliant; aftermarket pipes without the EPA stamp are citable.
Exhaust/muffler violation under G.S. 20-128: infraction with 50 to 200 dollar fine plus court costs (~188 dollars). Loud stereo beyond 25 ft: civil citation 50 to 100 dollars. Points not assessed on license. Repeat offenders may face equipment-inspection order.
