I follow SEMA activities and contact my reps when necessary to get in my $.02. I got this msg yesterday... not happy.

Virginia Signs into Law Anti-Hobby Exhaust Noise Bill

Governor Glenn Youngkin (R) signed into law SAN-opposed legislation (H.B. 632) to reform enforcement of Virginia's exhaust noise laws. H.B. 632 repeals a 2020 bill which prevented law enforcement from stopping motorists solely for exhaust noise violations. Virginia prohibits mufflers that use an “excessive or unusual level of noise” and mandates that mufflers must be identical to their factory setting, comparable to factory equipment, approved by the Superintendent, or meets or exceeds standards of SAE International, ANSI, or the U.S. Department of Transportation.

In the next legislative session, the SEMA Action Network (SAN) will be seeking to implement a fair testing procedure and decibel limit for vehicle owners accused of unreasonable exhaust noise violations. Accordingly, please encourage others to get involved now by signing-up with the SAN without cost or obligation.

Thank you to those who voiced concerns with lawmakers about this effort.
