Cheers for the replies guys. Eventually the whole exhaust system will be done, but i'm looking to upgrade in stages. I figured headers first to keep the popo away for awhile at least, then cat and catback which i got quoted around $350 from my local store. I'm not buying anything Toda or Mugen for a d series, you're paying for a brand when essentially all that is better is the steel/ceramic/etc piping and name slapped on it. Technically speaking all pipes flow the same and you're only looking at max a 10hp increase with a brand name part anyway.

That's what i'm currently looking at. I'll be installing them myself, cause honestly, it's piss easy if you've done a set before. Adult size mechano pretty much.
