It depends on which county you live in. I live in Washington County and I do not have cats. As long as the CEL is off and all my readiness monitors (except one) are responding, I will pass inspection. There is no required check to make sure you have emission controls for Washington County.
I think this is the website you can check to see if your county requires emission control devices:
PA DEP I/M - Information for Pittsburgh Area Drivers
I'm guessing you live in the Pittsburgh Region (Allegheny, Beaver, Washington, and Westmoreland Counties) and it doesn't look like any of those counties require cats. Just make sure that you can keep you CEL off with the test pipes. You may need to put on O2 sensor extenders on your downstream O2 sensors if you are getting a CEL.
