If it moves or removes any cat's from their stock location it is illegal in Cali, if it doesn't, it's fine.

That's the rule, you will fail on a visual inspection if it moves the cat's or replaces them. If not, it will pass on a visual. As far as the roller's go, it will still pass as the muffler has no effect on emmisions.
