The best way to do this is to find an Exhaust/ Smog shop in your town. They can install one, or if you know what you're doing buy on from your local auto parts store and weld it on yourself.
Find a junk yard and get one. It's a simple mechanical part and they usually don't go bad for a long time. The junk yard will want $30 for it and the parts house will want about $300. I work at a parts house also.Where to go to buy a Catalytic Converter?
