well I am new here but thought that this would be the best place to ask your opionions, I purchaced an awd 93 impreza L wagon (white) and am having a very difficult time finding aftermarket parts for it.

Which exaughst, where? price?
Intake?
body kit? (cant seem to find anywhere)
rear wings (small, like on wrx wagon)

any help would be great. thanks!

Lots of exhausts, anything that fits an GC RS will fit your car.
Buy a K&N or an Amsoil filter, and take out the snorkus.

Look up version II STI wagons. If you could make your car look like that in North America you would have something no one else (or at least very very few) have over here.

The wings pop up on eBay from time to time, probably your best bet.
