Folsom FAQ
Is a loud exhaust illegal in Folsom?
Yes if it's louder than factory or exceeds 95 dBA at the tailpipe. Officers can cite under CVC §27150 and require you to pass a BAR referee inspection to clear the citation.
What about motorcycles?
Motorcycles are subject to the same noise limits (80 dBA at 50 ft passing) plus EPA tailpipe stamp requirements. Aftermarket pipes without EPA stamps are citable.

Only if they exceed the CVC 27150 or 23130 noise thresholds. CARB-approved systems that meet limits are legal.
