4 things to start (not in any particular order)
1. B&M shifter - trust me.
2. KKM or similar intake - gives a little power (not too much but its there) looks good and sounds good (on the cheap you can get a K&N and clip it to your MAF for a similar gain, but it doesn't look nearly as cool)
3. Aftermarket cat-back - Bassani or Borla or you can roll your own (I did, I used vibrant components)
4. Y-pipe - Sho-Shop or YoDude (don't know where to get these, ask Aussie SVT)
After that go for suspension and brake stuff.
