Yes, cat's burn even more of the unburnt fuel left over from the combustion process. And in the case of 93 and older fox bodies, the air tubes actually pump oxygen into the cats to keep them nice and hot.

However, at WOT, the cats don't work nearly as well. Don't know how, if any, differnent tailpipe o2's sample the air behind the cats.
