Exhaust: bang for buck a Truebendz is probably your best bet
Intake: a simple MAF adapter and a K&N Filter does the trick, I have the re-0910, but the most sugeussted is the ru-3530 i believe.
Body Kit: There aren't many offered, even less look good IMO, the only one i've ever seen look good that isn't fabricated is the C-27/Kaotic kit from Andys Auto Sport.
As for anything else, it's all about budget, unfortunatly Tours are expensive cars to "tune" since there isn't too big of a market of these cars vs. something like hondas. The average cost of a good performance mod will run probably around $200.
Other mods:
MSDS Headers, Weapon*R's are cheap crappy knock offs from what i've read
Y-pipe: you can get these through Truebendz
Suspension: the cominations are endless, it also greatly depends on what you want, you want slammed get Intrax springs or adjustable coil over, make sure to buy new struts as well.
I'm sure there will be other sugestions but this should easily be enough to get you broke for awhile
