I just replaced one on my 1995 Grand Marquis. You have a couple of options. The factory origina ranged from $179.00 to $900.00. Aftermarked ones ranged from $80.00 to $361.00. I found a garage that put an aftermarket in for me for $117.23. They had to do some cutting and welding to do it. It seems to work fine so far.

You do not fix a defective Catalytic Converter, you replace it. A replacement converter will cost from $250 to $400 depending on brand and quality. OEM will be around $300. Labor costs are not included.
I just had one replaced for $762.00.
