Keep stock Cats or go AM ones?

I'm currently installing Pacesetter LT headers and just wondering if I should keep my stock dual catalytic converters or go with some aftermarket ones? I don't have a ton of money right now. I have to still pay the muffler shop to weld me a custom Y-pipe. So since they are going to do the Y-pipe, I'm just figuring out if I should have them tie my stock cats into them or some aftermarket ones?

Absolutely get rid of the stockers. High flows work great!

I have a pair of Random Technology cats and they work really well. Noticed a big improvement in my 1/4 times.
