I'm in San Diego as well. Do you run an x-pipe?Yup, no DMV inspections in California for MC's. However, CHP does target bikes with loud pipes. Typically they use it as a tool to stop the OMG 1% type of rider but I've had some experience with them stopping us law abiding bikers.
I'd suggest keeping your exhaust in a way that you can revert it back to stock. If you do get a citation from CHP, it will likely be a corrective cite. Once you show the correction to your equipment, you'll be signed off. Of course the processing of corrective citations isn't free so you'll be "taxed" a bit one way or another.
