[Norcal] '06 Prius Cat Stolen - Help Needed

In Oakland - two weeks ago our 180k mile gen 2 prius got its Cat stolen. As many other members have mentioned, at this point the repair may be more than the worth of the car. Also, just replaced the 12V a month ago...

Was wondering if we can find an aftermarket cat for the Prius (and someone that can help install it) so that it can last for 12-14 months while we can shop around for another car. Would just be used for local / groceries / errands.

Thanks! (Thoughts going out to all the fellow "cat-less" Prius owners)
