All exhausts systems must have an EPA sound emission labels if they are made after January 1, 2013
A new California law requires street motorcycles registered in the state and built on or after January 1, 2013, to have an exhaust system label certifying the motorcycles meet federal sound limits, the American Motorcyclist Association (AMA) reports.
On Sept. 28, Governor Arnold Schwarzenegger signed into law Senate Bill 435, sponsored by Sen. Fran Pavey (D-Agoura Hills). While motorcycle manufacturers have been complying with the federal law since it was effective in 1983, the new law now makes it a state crime to operate any motorcycle registered in the state that was built on or after Jan. 1, 2013, that doesn't have a federal Environmental Protection Agency exhaust system sound emissions label.
In addition, the law requires aftermarket exhaust systems made on or after Jan. 1, 2013, to display the EPA sound emissions label, and therefore applies to individuals who seek to replace the exhaust system on affected streetbikes.
Violators face fines of up to $100 for a first offense and up to $250 for subsequent offenses. Judges have the discretion to dismiss the fine for first-time offenders if the violation is corrected.
In 1972, Congress passed the federal Noise Control Act, which required the EPA to set sound standards for a number of products. It took several years, but the EPA eventually wrote rules affecting all new motorcycles sold in the U.S. beginning in 1983. Those regulations, which still stand today, required that all street-legal motorcycles be limited to 83 decibels at that time, with a stricter, 80-decibel limit imposed beginning in 1986.
The AMA has long maintained a position of strong opposition to excessive motorcycle sound. In September 2009, the AMA developed model legislation for use by cities and states seeking a simple, consistent and economical way to deal with sound complaints related to on-highway motorcycles within the larger context of excessive sound from all sources.
