I have the exact same thing happening to me, But its the two cats in the y-pipe. Mine is plugged so bad the car won't run when it is above 30deg outside.
I am frantically searching for replacement and/or a fix. Unfortunately I am in Canada, "Monteros" are not that popular here.

I have found something on ebay, but it specify's for a 2004, mine is a 2003! FFS! I wonder what the difference is?

As for the large cat, I bought on from Rock Auto here in North America

Still having a lool around with not much luck found a couple of second-hand units but they are off NP's that have about the same mileage so would probably fail soon anyway don't think its worth the $250.

Why not drill out your upstream cats with a drill and use o2 extenders to keep ecu happy. Replace the downstream one on main pipe.
