best choice for high flow cat?

[flux]

I'm looking for a high flow catalytic converter for my 92 Ka24DE s13 to maintainemissions while improving performance. Heres what ive been looking at so far. The price ranges arnt very far from eachother at all so it just comes down to the brand. Let me know what you guys think i should go with Plans for the car currently are stock motor with bolt ons I/H/C/Ehttp://cgi.ebay.com/ebaymotors...wItem

Well all of those are 2.5" cats. If you want to open things up a bit to go with the exhaust then you might wanna get a 3"er.I am running a magnaflow from pdm racing. It was a bit more expensive but came with the flanges already welded on.

i'd avoid catco for emissions testing in CA. catco's are only 2 way, and you'll want a 3 way catalytic converter to keep the NOx at bay.
