Looks like part of the muffler to me. You should have it replaced it could end up obstructing the exhaust.
I found pretty good video about changing the muffler here. As Larry said, it is not the catalysator but the part before the catalysator. It looks like something that even an amateur is able to do. In Finland, the cost is about 60EUR for the part so not expensive part. (source of the image) Terminology muffler = äänenvaimentimet, takapönttö ...

I don't think there is any real external difference between the California and non-California ...
I got the same code with 2000 tundra. I found you need to compare HO₂S Sensor 2 to engine load. If engine load is low enough, the sensor voltage should be 0 for a period of time as well. When decelerating, engine load is low, rpm is low and throttle position probably is close. Not a technician, just leaning.
