2.25" is too large for a stock 22RE, but you can probably have a muffler shop put reducers on each side. I am not sure what that would do for you performance, but it probably would not lower it.

I'm not sure how accurate this is, but, if it's smaller it might not have the correct capacity to successfully catch all the toxic gases. Correct me if I'm wrong. How strict are the IL smog checks?

This particular cat is actually bigger than stock. It should catch all of the toxic gases as long as it is in good shape. If you install it, you might want to go ahead and upgrade the rest of the cat back exhaust to 2.25" with a free flowing muffler. 2.25" is suppose to be the maximum size for the 22RE without lowering your low end torque.

You will have to measure, but the 22R has 1.75" pipe. I believe the 3.0 has 2". Check out this website for more information:
