QWR believes that “Quiet is Cool” when it comes to the use of sound compliant exhaust systems for both street and off-road vehicles.
Passage of AB 1824 in 2018 basically amended California’s existing 2003 sound law by replacing the “fix-it” ticket aspect of the old law with the option of getting a certificate of compliance from the CA Bureau of Automotive Repair (BAR).
AB 1824 retained the existing sound level of 95dBA using the SAE J1492 sound test format. SAE J1492 is similar to the SAE J1287 sound test for OHVs which has a 96dBA limit.

QWR will be reviewing this issue with SEMA and other stakeholders over the next few weeks. In the meantime, if you wonder if your automobile or light truck (under 6K lb. GVW) is too loud then ask yourself these simple questions?
One- Does my motor vehicle sound too loud?
Two- Has a neighbor or friend told me that my motor vehicle is too loud?
Three – When I start my motor vehicle early in the morning do the neighbor’s dogs start barking or do I set off the car alarms of nearby motor vehicles?
If the answer to any of those questions is YES – then your motor vehicle IS too loud and will most likely test above the 95dBA limit.
