It needs to go before the cats to be accurate IMO.

Behind the cat, your WB will read slightly leaner than pre-cat. In other words, a pre-cat AFR of 12.3:1 would read 12.5-12.8:1 post-cat. Under the same conditions every time (warm up time and same bung), your WB will be fairly precise and give pretty reliable readings. Tune for the limit post-cat and you'll actually be just slightly on the safe side.
