Exactly. The 05 HIDs will go for a premium, so if you want the JDM look without the hassle of prying open your perfectly good pair of HIDs and risk not sealing them properly, this is a viable solution and you can probably sell yours for a bit of cash to offset the cost of these.

Oh my god those are sweet. Ive done a few searches and couldnt find very much as to how to wire these up in an 04 WRX. That is my main concern about buying these. I dont want to spend that kinda money and wire them up wrong. Can you point me in any direction? Thanks
1) Go to http://www.chaiofangimports.com
and spend $55 to get the piece they supply that will make the JDM STi HIDs plug and play.
2) If you are a do it yourself kind of person, here are some instructions that others provided:

I installed the STi HID headlights into my 2004 WRX a few weeks back. The installation is very easy...It is very straight-forward. I assume that you know how to remove & replace the headlights, so I won't go into that. I also assume that you know how to use a soldering gun/heat shrink tubing, etc.
The standard disclaimer applies - This is what I did on my car. You should verify everything before performing this modification. I am not responsible for any damage or problems associated with this modification. Consult the service manual wiring diagrams WI-135 and WI-138.
By the way, the 2004 STi headlights are different from the standard WRX lights. The reflectors and bulb shields are different. I had a Catz HID kit on my car before switching to the STi lights. The Catz HIDs put out more light, but the beam pattern was not very good. The STi lights have an excellent beam pattern.
Here's what I did:
1) Disable the DRLs by disconnecting the DRL module behind the glove box. This is important.
2)On each headlight, there is a short pigtail lead that goes from the ballast to a black 2-prong plug. Remove these black plugs. You will then have one red and one black wire coming out of each ballast. The red are your positive leads and the black are the negative (ground) leads.
3) Solder a 18"-24" length of black wire onto each of the the existing black wires an put a ring terminal on the end of each.
4) LEFT HEADLIGHT (driver's side): Cut off the existing grey plug that plugged into your low beams and remove a few inches of the black protective tubing. You will have a yellow/red wire and a red/blue wire. Cap off the yellow/red wire - you will not be using it. Ensure that the red/blue wire is positive and is energized when the headlight switch is in the on position. Solder the red/blue wire to the red wire coming out of the ballast. Use heat shrink to weatherproof the connection. Take the black wire with the ring terminal on the end and attach it to the ground point next to the battery.
4) RIGHT HEADLIGHT (passenger's side): Cut off the existing grey plug that plugged into your low beams and remove a few inches of the black protective tubing. You will have a yellow/red wire and a blue/white wire. Cap off the yellow/red wire - you will not be using it. Ensure that the blue/white wire is positive and is energized when the headlight switch is in the on position. Solder the blue/white wire to the red wire coming out of the ballast. Use heat shrink to weatherproof the connection. Take the black wire with the ring terminal on the end and attach it to the ground point next to the air box.
5) Plug in the high beams and clearance/signal lights on both sides.
6) Properly aim the lights.
7) Enjoy your HID lights.
I hope this helps. Let me know if you have any questions.
Once installed, here is how level your HIDs:
Here is what is what you need to do to adjust/aim the HIDs once installed:
Locate the headlight beam leveler motor on the back of the headlight assembly. There will be a white plastic 8mm hex head protruding from the back of the motor assembly. Turn this hex to adjust the level of the beam. I believe that turning it clockwise raises the beam.
The Subaru manual states the following for adjustment:
1) Put the vehicle on a level surface
2) Verify tire inflation is correct
3) Make sure gas tank is full
4) Bounce vehicle to normalize the suspension
5) Be sure someone is in the driver's seat
6) Set the leveler switch to 0
7) Park the vehicle 10 feet from a vertical surface (wall).
8) With the vehicle 10 feet from the wall, the top of the beam cutoff should be 23.93 inches off the ground.
