I thought the pre-cat o2 sensors were to manage fuel mixture and the post-cat o2 sensors were for emissions?

If you have to have Cat converters then you do need adaptation of fuel mixture so that the Cat converters function correctly.
The air /fuel ratio that allows Cat converters to work is not the same air/fuel ratio that makes power.
You can't have both at the same time.
Pre-cat O2 sensors are to manage fuel mixture "for Cat Converter function" Post cat O2 sensors monitor Cat converter function to make sure pre cat O2 sensor are doing there job.
They are both for emissions.
Google: Catalytic Converters find the Wikipedia article on Cat Converters.
Read the whole article. Pay particular attention to the segment on "Three way Cat. Converters".
