Get an oxygen sensor bung plug.

Even the right size bolt will do. I recommend putting some anti-seize on it, just in case you even want to take it off for whatever reason.

Sorry, misread it.
Go to a muffler shop, they can drill and weld on an additional oxygen sensor bung. Shop around by talking to the guys, as some guys will do it cheap, like $20.

my bad i was thinking VW (my day job), lol....your right. Alright, drill a hole and weld a bung. Should cost you $25 at the most.
Or buy a test pipe off ebayw/ the #2 bung and space out the rear oxygen sensor so it doesnt cause the P0420 DTC. This is the set up i was running til i swapped engines

Re: URGENT! HELP WITH EXHAUST
If your exhaust is Stainless Steel you will want to put a SS bung on there not mild steel. If it is a mild steel setup, you can cut out just the bung off the Cat if you want. It's probably still easier just to buy a Mild steel bung for $5-$10 and do it right.

Re: URGENT! HELP WITH EXHAUST
The reason you only have one bung is because the 94 was OBD1, which doesn't use a secondary O2 sensor. However, OBD-2 cars (95+) do use them.

Re: URGENT! HELP WITH EXHAUST
Anything exhaust related tends to get seized up like that...constant heating and cooling is tough on parts. Probably rusted into one piece haha.

Re: URGENT! HELP WITH EXHAUST
yea i tried everything, i kno lubricant is advised against because its known to clog the pores on the sensor but as a last resort i poured pb blaster and liquid wrench on it, let it sit, then stuck that **** in a vice and it still wouldnt budge even with 3 people pullin on it, it just started to strip

Re: URGENT! HELP WITH EXHAUST
What brand?
Some of the none OEM secondary O2 sensors heater circuits don't seam to work well/last long. Just an FYI! So if your CEL happens to pop on after a bit that is what you may expect to be the problem.
