replacing the cat's

ok, so very soon I will be going to long tube headers, and I will be replacing the cat's with hi-flow units.....now, my question is this, there are 2 sets of O2 sensors, correct? If you are only putting on 2 cat's instead of the factory 4, what are u supposed to do with the other 2 sensors? Thanks for any and all help in advance

You'll still have 2 O2 sensors before the cats and 2 after.
