I plan on removing the exhaust piece that goes from cat to stock air cleaner.. but there is a vac line from that to where the 4x4 vac lines are.. can I just plug that port?

there is no vacuum line from the cat to anything. the only vacuum lines from that area are the ones from the t-case to the canister and then to the front axle. it might be a vent that maybe got melted on to the line or exhaust though

I don't feel like working on anything at this time so i sold my yj.

I believe that your two way cat had that hose which is part of you EGR system. If you remove the cat (why?) the EGR becomes useless. BUT if you still have the ECU controlling things it may mess things up since the ECU controls the EGR solenoid, etc.
If this jeep engine has been Nuttered (Google John Nutter) then removing the EGR pump/solenoid should have no effect on the engine performance.

Do you know what was good about the good old days? I wasn't good, And I wasn't old!

Senators and Congressman should wear uniforms like NASCAR drivers so we could identify their corporate sponsors....

I'm not removing the cat. I just wanted to remove that part as its just in the way and I'm not sure its doing anything. My egr isn't hooked up. I'm nuttered and have a 2150 carb. I was just curious what the smaller vac line on there is going to or supposed to go to. It looks like its going down to the 4x4 vacuum lines.
