B6 3.0 - how much should it cost (labor/time) to install o2 spacers on both exhausts? (Of course, my Audi mechanic is probably reading this).

Thanks!

Labor time would be about the same as replacing the rear O2 sensors. However, most shops probably won't do this for you for legal reasons since it will affect the emissions reporting.
