Default wrx exhaust for a 2.5??

Is it really true I can use a cat back exhaust for a WRX on my 02 RS? If so, which would be better (big hp gain, affordable, reliable)
Borla, Cobb or Stromung. As for the Stromung exhaust which mm do I go with --76 or 89?. Also would investing in Borla headers be a significant hp gain? I read average 10 hp and 14 lb/ft. True?!?
