Assembly Bill No. AB-1824 (Section 4) is looking to pass the following for 2019:

(4) .. Existing law requires every motor vehicle subject to registration to be equipped with an adequate muffler in constant operation and properly maintained to prevent any excessive or unusual noise and prohibits a muffler or exhaust system from being equipped with a cutout, bypass, or similar device. Existing law further prohibits the modification of an exhaust system of a motor vehicle in a manner that will amplify or increase the noise emitted by the motor of the vehicle so that the vehicle exceeds existing noise limits. This bill would include, among those conditions that are disqualifying, a violation of the above-described requirements related to mufflers and exhaust systems.

There is a petition against this law here: https://www.change.org/p/jay-obernol...-in-california

Save your exhaust!
