things to note
make sure you buy an aftermarket/sti uppipe with you exhaust setup to remove that catalytic converter as well. its a pain in the ****, but its worth the spool and power. upipe is cheap, usually like 100~200 bucks.
you can get a quick-n-easy but not exactly the best tune by getting a cobb accessport. this is somewhat of a DIY reflash. costs about 690 new and 450~500 new.
as with any exhaust system install, make sure you buy all necessary gaskets.
header to uppipe
uppipe to turbo
turbo to downpipe
downpipe to catback
and any others i "might" have missed.

that was skaggs yeah?

Redils16,
Alex(sauuce) made some good points, and i'll try to add a few more things since my last post was very vague at best.
A catback, like you said, won't affect the emission part of smog, so it's problem free, but you get little to no performance gain.
A turboback is more work, but if you've got some mechanical experience, it's not difficult. A turboback alone won't give any performance gains, and in fact it's bad for your car without a proper tune.
Alex mentioned doing the uppipe as well as the turboback. The price of an uppipe is cheap, but annoying to put on. It's very much doable, but will take quite some time, depending on your experience. Again, this is bad without proper tune.
As for tuning, you'll have to look into what you want to do, but i'll name a few common ways.
Accessport-One of the more common/popular tuning method. It's a small plug and play device you can install yourself, and after reflashing your car with it, you'll be good to go. You'll gain noticeable power. There are excellent tuners in norcal that can further tune your car once you have an accessport, called protunes. This tune is more personal, and tailored to your car, giving you more performance and a smoother powerband that an off the shelf map on the accessport is not capable of.
OpenECU-If you search for this, you'll find plenty of great articles that can explain it in details. To put it simply, there's no device to buy, just need a cable and a laptop. You can learn to tune yourself, or pay someone knowledgeable to make you a personal map. It's more personal than the off the shelf map that comes on the accessport, but most well known tuners in our area will not deal with this type of tuning. So this is cheaper, but less local support.
Standalone- unless you've got complicated set ups, no point in spending $$$$.
Ecutek- you need to pay a license fee of like ~$600, no device, and an additional ~$300 for every tune you get after that. This used to be popular a while back, but now i hardly hear about this. This is done at authorized tuners.
For your purpose, look into both accessport and openecu. I used to use an accessport, so i'm partial to that. If you've got more questions, feel free to ask. It's probably better than me rambling about stuff you don't care about. Anyone can feel free to add/correct, but lets keep it simple.
