Just got this catback and crossover x-pipe installed:

Love the overall tone - much deeper, and very smooth, with no drone while cruising. My only "issue" is it's not quite as loud as I would like. Seems just a bit quieter than, say, the borla stinger catback I had on my 04 cobra. The mufflers of that kit and this new one look basically identical, but the new ones use a "multicore" setup.
Anyways, just curious about the concept of opting for some high flow cats. Firstly, this borla kit requires the cutting (shortening) of the stock midpipe, so the option of a catted x-pipe is out - unless i wanted to chop up a brand new $600+ pipe. This is why I'd just replace the cats. So how much louder should I expect a set of cats to make the catback? Would drone be likely to increase a lot, because that would kinda suck. Also, would metallic cats be a good idea? (for reference: http://www.americanmuscle.com/pypes-metallic-catalytic-converter.html). I hear they flow well, but I see many listed as "off road", and I'm gonna have to pass e-tests in another couple years. Also, I've seen a few aftermarket cats that use clamps if you don't want to weld - worth it? Figured that could let me try a set and if it was louder than I wanted to go, I could just weld the stockers back in.
Anyways, lots of questions on my end, so thanks in advance for any advice.
