Performance comparison high flow or resonator?

I'm planning on putting a high flow cat w/ my headers-exhaust set up.

1. What's a good brand for high flow cat?

2. Also, I am running a 2.5 inch exhaust w/ Cosworth header, and will it be better to run a 3inch cat or 2.5" cat?

3. Which is more restrictive a resonator or high flow?

4. Which one will make the car quieter?

The resonator will deff. make the car quieter, it may add a little although I don't know if it will add power, I don't think the cat will help with toning the sound down, although it will add some power and allow the air to flow freely. I am going to install a Magnaflow hi-flow cat, or magnalfow resonator in place of the stock cat.
