Someone cut the catalytic convert off my 1990 4Runner :(

Hello everyone,
I found this forum while looking up what to do about my problem and none of the other CC threads had the info I needed.

So about 3 days ago I started my '90 and thought I had a hole in the muffler...turns out someone took a saw and went straight through the pipe about 6 inches in front of and behind my CC. There are 6-7 other 4runner in the whole complex but only mine got hit this time. The first shop I quoted said they want $1200 to fix it :mad: but I had some luck. In my apartment building is another 4runner owner (a really nice '94) who has his own shop. He was really upset about what happened (he thinks he is next) so he offered to do the labor if I get the parts.

This is in Colorado, so I can't get a used one from a junk yard. I did find a fair price online on a new one but after 3 days I just can't figure out all of the parts I need. How or where can I get a list of what I need?

-The actual CC (check)
-The two pieces of exhaust pipe that were cut
- The two O2 sensors (the wires were also cut)
-*I have been told by someone who said "I think you need", that I need some kind of single use gasket to connect the pipe and CC. Again I was told this is the hardest of the parts to find and the most expensive, but I have no clue.

I love my car and I need to get it fixed, but as cheap as humanly possible. I graduated college last week, which just means I'm unemployed right now lol.

Sounds like you need a catalytic converter (a universal weld in cat will be cheaper), exhaust piping that matches the diamater of your existing pipes, O2 bungs and O2 sensors (you can find O2's with bare wires on the end which would splice right into your cut wires, and are WAY cheaper).
 
Well it looks like I only need one sensor for the 1990 and it's in front of the CAT.
The CAT and the one O2 sensor are on the way. The CAT is a universal from Eastern Catalytic and the O2 sensor was pretty cheap as well. The exhaust pipes will cost me the most so I guess I'll see if I can go raid a junkyard in the next few days and find the right pipe.
Thanks

Does the eastern Cat work with the stock sensor?
