Default Questions about Cobb AP

So I'm finally considering getting a Accessport for my 05' WRX. Just had a couple of questions first,

Are you able to use other name brand turboback exhausts / intakes other than Cobb if you decide to flash your ECU to stage 2?

I'm especially asking about the intake, since on there site it says that a stock or Cobb intake is required for the stage 2 maps. I'm new to this whole tuning the ECU thing, just trying to get some more information about it.

As long as the downpipe is a 3" Catted downpipe the OTS maps for stage 2 should work fine. I'm not too sure for the 2005 STI but I'm pretty sure cobb offers a stage 2 with stock intake aswell. Intake is however the most sensitive item when using a Cobb map. Make sure that if a Cobb intake is required that you get the exact intake.

For exhausts, the map notes expressly say for Cobb turbo back or SIMILAR. Meaning similar in size and catted.

For intakes, you need a Cobb or AEM. Intakes are generally a waste of money anyhow. If you have an intake aside from the 2 listed, you will need a protune or e-tune.

Do more research, it's all been spelled out before.
