O2 sensors

[HASFANGS]

I'm swapping in the catted Bassani X pipe this weekend, and wondering if there is anything special about swapping over the O2 sensors?

Do you clean them? Replace them? Is there a gasket or sealer required?

Thanks in advance.

No sealant required. A 7/8" wrench and that's it. I swapped my X pipe on my 98 and it had 50K miles so I went ahead and swapped the O2 sensors (all 4). Depends how anal you are and how many miles you have on the old ones. They are consumable and don't last forever though.
