Starting the first of this year, police in California officially have the authority to ticket motorcyclists who ride motorcycles with non-compliant exhaust systems under SB435, the Motorcycle Anti-Tampering Act.
Signed in 2010, this new motorcycle exhaust
law isn't the first to hit the California law books. SB435 is a law meant to support already existing motorcycle exhaust restrictions by allowing police to ticket motorcycles that are parked, ridden or used for any other matter that have been manufactured after January 1, 2013 and have an aftermarket exhaust system or any motorcycle that has a motorcycle exhaust system
manufactured after January 1, 2013 that does not display a label directly on the exhaust system showing that it adheres to previously instated noise emission standards.
