The cat has a flange on it and so does the mid pipe. There are 2 spring bolts connecting the 2 and the donut thing is a gasket. You can replace this if you want but most likely you can resuse it.

You will be able to bolt the header/cat setup to your stock mid pipe if the flanges match up. only way to find out is to crawl under your car and find out.
I'm sorry about the post. Agreed, it is kinda confusing, hahaha. I currently have a stromung muffler with a stock midpipe, and am going to be installing the brullen header/cat. I'll probably do the install and go to a muffler shop next weekend, so I can crawl under the car then. Supposing the cat and stock midpipe don't bolt up, the I won't be able to install the header myself and will have to take it to the exhaust shop, which would suck.

So, what is the size of the stock midpipe? Like I said, I think my muffler piping is 2.25" so a 2.25" midpipe would be fine as you said, but why would a 2.5" midpipe kill some of my torque?
