If you took your stock y pipe to an exhaust shop and had them cut it so it can fit with the headers you will be able to pass the sniffer...
Any off road y pipe sold along with the headers however will not pass. I think your best option is to have a y pipe fabbed up for you with stock cats or hi-flow cats so you can still pass emissions.

Still won't pass in Cali...you're not allowed to move the cats from their stock location in any way, shape, or form. Unless you get a system that's clearly marked "legal for sale in California", you're out
I don't believe that there are any LT systems that are legal in Cali, even the ones with cats...stupid laws IMO...as long as the system can legally pass emissions it shouldn't make a difference, but unfortunately the laws are made by politicians, not automotive engineers or master technicians 
IIRC, the ASM headers used to retain the factory y-pipe, it just needed to be hacked up before the cats (which didn't even move from their factory location), and they weren't legal for sale in Cali...
