Any store like Auto zone or Advance should sell oem style ones. Aside from them you can buy universal ones most places that sell aftermarket exhaust components. You could also try a salvage yard but you can never tell how long it will last.

I just did the same fix, google a magnaflow direct fit catalytic converter for your car, it should run 3-400 bucks and only takes about 45 mins to install, that's what I put on mine, Autozone and such stores do not deal with catalytic converters like you need I checked them, also it is illegal for salvage yards to sell used cats because of government regulation they have to cut them off a car and send it to scrap as soon as they get a vehicle in.

If you don't have to go through emissions then you can order a $6.00 bypass diode on E-Bay that tells your computer everything is running normal. You just wire it in line with your O2 sensor. Then just cut off your CAT and weld a pipe in and there ya go! More power and better fuel mileage and you don't get raped on a new CAT. They are way over priced and you will get labor charges on top of that. If your not exhaust welding savy, take it to a local exhaust shop and have them weld a pipe on for you. But be sure to cut the CAT off yourself cuz they are not allowed to do it. For the record, this is for off-road purposes only:)
