Help with choosing an o2 housing.

i know this is an extremely beginner question. but the fact of the matter is, my GSX has a custom down pipe with an o2 housing delete... so i have never had to research about buying one. i just did a quick search on extreme PSI, and it seems as if there is about 10 different styles to choose from. how do i know which one i need? and which one is the best?

You choose based on the turbo, exhaust, internal/external wastegate, pricing, material, etc. You need one that will work for your application.

thats easy enough. are there any benefits of going with a open dump vs a recirculated? i think the best thing to do is to wait until i have the turbo back, and have this other car so i can measure everything to make sure it will work.
