you will lose low rpm power with a turboback and gain few hp on high rpm power.
i'd get a magnaflow cat-back if i was you, i bought one for my STi 2012 and it sounds very nice. and once you get a bigger turbo/tune, then buy the downpipe.

Talk to your specific Subaru Dealership, only they can tell you what will cause a warranty claim to be denied (warranties cannot ever be voided).
your dealership are the ones who will be processing any kind of warranty claim you will every have, they will know more than any type of forum.
and if you have a good dealership, like one that yearly rents out a race track for you, then may be willing to give you a bit more slack
i called mine before installing my cat-back.
answer: no mods will ever void the warranty.
only thing that WILL void your warranty is if your mods are the causes of the broken things.
Denied, are you a IWSTI member?
