Correct, although there are two paths you could take:

(1) Do what I did and use the factory STI front shaft with the STI rear outer CV and STI front inner CV. To do this you need to have your 5-speed modified to be able to accept the stub input. I believe this in only possible if you replace the center diff with an LSD diff.

(2) You can have a custom axle made by the driveshaftshop guys that has the STI outer spline (to fit your rear outer STI CV) and the WRX front inner CV spline (to fit a pair of front inner CVs you buy).

In that second case you have the advantage that you can run any 5-speed, and you don't need to worry about pushing the wheels out because the axle shafts will be the perfect length.
