1998 986 5spd 75k miles driven year round in NE as daily driver-

At some point soon I will be dropping the exhaust. I got a gently used muffler cheap. And after market headers. I assume the cats and the 02 sensors though fused together, will still have some life left. I have ordered all the bolts, clamps and harware since they are all solid rust.

When I have the exhaust apart is there anything I can do to maintain the cats and prolong their life?

I have taken to painting rust prone parts with high temp paint(500 degrees or 1200 depending on part), powder coat small ones, or anti rust paint for others. So I figure I will paint the outside of the exhaust parts. But with the cats, can you vacum or wash them out? I assume painting inside is a bad idea.

I want to preserve those expensive babies. If anyone has gently used ones they want to get rid of, let me know. Thanks.
