You have an O2 sensor before the cat. Then you have one after. The one before the cat is used by your computer to adjust all the air-fuel mixture ratios. The one after is just to verify that the first one is working properly. They do make an O2 sim, i think it called. That actually takes the place of the 2nd O2. Thus, you can do whatever you want to the air-fuel mixture without throwing a code.

His a 93 it sill falls under OBD1, if doesnt use an after cat o2 sensor. you should'nt have any codes pop up being that there is no after cat sensor, however i never recommend gutting the cat because they are there for a reason, im not slamming ya about this but its illegal to do it.
