it all depends what you have on there already. this is what i could tell you to do first ..

[hp]
- COLD AIR INTAKE. it's everyone's first mod, and it's the fastest and cheapest way to gain hp.
- exhaust. depending on your existing piping diameter, you might not need the full cat back.
- headers. this is last because it's ususally the most expensive.

[exterior]
- if you only have hubcaps, DO NOT GET THE BODY KIT FIRST. i hate it when i see that on the road. get the wheels first.
- after the wheels, go for the drop with adjustable coilovers, new shocks and a camber kit.
- finally ... the body kit. if you scrape too much, you could always adjust your ride hight.

[audio]
- remember ... somewhere between the mods, you're going to get bitten by the audio bug ... hard.

you really get what you pay for. if you wanted to go cheap, then your car will look cheap. there's nothing wrong with finding deals, but it's your car and these mods are usually long term investments.
