you dont want to do that. thats what makes your 5/6 ports work you can remove the other 2 cats but leave the main or you can buy a test pipe ment to go in oplace of the cat so that they still fuction

There were no survivors
Remove the airpump as there would be no point in having it on if you remove the cat. It'll free up ~1-2ish hp and improve engine response a little as well. One less piece of parasitic drag. Assuming you have a series 5 (89+) RX-7

cut it off and plug it, its one hell of a vac leak. like posted above wire up an rpm switch to open the port on an s4. mine are just wired open right now, because i have a straight through exhaust and no money or time to wire one up. that will be done shortly

no, you plug the lines, a srew(small line) and a spare socket(big line, it is a 14mm i belive is what i used) it what i used. Prolly not the best way to do or the right way to do it, but hey, its what i had laying around at the time.

Since I know you have a S5 I say block it off. The ECU controls the 5th and 6th ports anyways so as long as you don't remove your air pump, you should be fine.

If you don't want to use them, remove them completely (sleeves also) and block it off (giving it unrestrictive air flow in the engine).

I'm not saying that that is the final solution. i just did that for the time being and focused on the other problems of the car. what do i do with the lines if i want to get the ports working again?
