Impreza WRX STi Pre motor swap mods?

my girl friend is planning on swapping the motor in her 2.5rs in about a year. so to keep the cost down, we are trying to do things to the car now that will aid the motor swap. we would also like the RS to sound better right now, and maybe pick up a few hp. we are thinking about having a local shop weld up a cat back exhaust (whats a fair price?). the problem is we dont want to change the exhaust again later on. so what size piping would you guys recomend. im leaning twords 3in, yes i know 2.5 rs' dont really like piping bigger than 2.5in, but that might be on the small side if she puts in a jdm motor at a later date.

were planning on buying the muffler and resonator ( should even we put a resonator on?) online, and taking them into a shop to be welded in. any recomendations on mufflers or places to get them... and if you think we should put in a resonator. were looking for better/ deeper "boxer" sound, but we dont want rasp.

also any other mods that we could do now that a turbo motor could use? thanks for reading the long post.
