Catalytic Convertor Question - Need Help

Need to replace the convertor on my '93 and was wondering if anyone can help me out. The exhaust that's on there now is totally stock. Looking at the options i have for the replacement and have come across the following:
  • 2in. female flare inlet/2 in. male ball outlet
  • 2.5in. female flare inlet/2.5in. male ball outlet
  • and then some options that don't list sizes at all

Can anyone tell me which one i need? Or if it even matters? Like i said, the car is all stock. Has the 3.8L.

Hope someone can help me out. This is the last thing i need and then it's on the road! Thanks!

You don't live in Nazi Cali so buy the magnaflow 3 cat front y-pipe from summit or take you car to a quality exhaust shop and have them make you down tubes and put on high flow universal cats.

Since 95 and older vehicles are still tested by two-speed tail pipe testing and visual inspections in most states that wouldn't be a good idea, but it's your car if you live in an emissions free county and wish to hack them off and break federal law that's your perogative. On 96+ obd2 vehicles and vehicles that are in emissions exempt countys with removed catalytic converters, or for off road use only vehicles 02 sensor simulators/eliminators work well and serve their purpose.

Yeah guys, i live in Ohio(not Nazi Cali, but compare it more to Russia; never sure which side they want to be on...) which sporadically lets counties choose for themselves if they want to test for emissions. The wonderful county of Summit where i live does. Which means they'll do both the visual inpection and the tail-pipe test. In any event, the plan for this 'Bird is to stay stock anyways so i'd want them on. I just need to know what size to get!

Magnaflow lists both sides as a 2.25" inlet/outlet.
