Is it possible for the pt to run without a cat? I think it would be, but I was told it depends on where the o2 sensor is located. I would like to try out the straight pipe idea, but I am curious as to if it is possible. I hear people saying that running a straight pipe improves power and sound. I am aware that it would not be smog legal, but I am thinking about giving it a try.

I wouldn't run a n/a PT without a cat. It would be very loud to run a straight pipe. You can run a straight pipe with a turbo but a n/a engine likes back pressure and a straight pipe could actually make less power. A high flow cat would be an idea. Not only would it be illegal but the fine for not having a cat is like $25,000. You also might think about a cut out. A cut out works by allowing you to use your exhaust system and with a flip of a switch the system is blocked off and your exhaust goes out a straight pipe.
