The air/fuel ratio is affected a bit by being after the cats. I take this into consideration when adjusting the fueling tables.

We usually even use rear o2 bungs even after cats. Either method works tailpipe or direct fit. I have recommended to some to drop their y-pipe or x-pipe and have us weld in a bung direct to the header or pre-cats for better tuning purposes. However, not everyone wants to spend the 1-1.5 hr of R&I & welding labor to put in a bung, and I don't blame them.
