Georgia Vehicle Exhaust Noise Laws

Many car enthusiasts decide to modify their car’s exhaust system, but there are laws governing the noise limit your vehicle can produce. The section below outlines relevant laws and legislation pertaining to car exhaust noise laws in Georgia.

Georgia legal exhaust noise summary:

Exhaust system modifications on vehicles registered in Georgia must not cause “excessive or unusual” noise.

Essentially this means many exhaust system modifications frequently done on sports or racing vehicles can be considered illegal. If you install aftermarket exhaust modifications make sure it does not produce excessive noise.

Georgia laws do not specify noise limit in decibels, therefore the law is open to interpretation. During vehicle exhaust inspections, exhaust noise is not checked.

The following law excerpts are from Georgia Vehicle Code § 40-8-71.
