Subaru EJ20 Headers?, Who's using what? Too many options! Options

Who's using what?

I'm finding a TON of options on eBay that range from $125-$800. I have no clue what the real difference is though.

Equal Length Headers or Unequal Length Headers?

Am I looking for a new oil pan too, or will the stock (2003) work?

Differences in the Turbo Pipe?

I want to buy now...just don't want to get the wrong thing and regret it later when it doesn't fit with what I'm doing.

I realize that I'll be hunting for an exhaust too, and that it'll likely need to be a custom built pipe, but the rest of the stuff seems to be pretty important.

Six or four? Turbo or naturally aspirated engine? You mention a turbo pipe, so I assume turbo? I have a WRX engine, used a stock STI exhaust with the WRX turbo, then a custom pipe from the turbo to the valance. Exhausts are kind of project-specific, and a lot of the automotive applications won't work on a mid-engined car. They aren't expensive, so I'd suggest you start out with stock, get the car done, then go back and change things you think need changing.

Pan depends on how your cradle positions the engine. If you need to put in a bump-out in the trunk to clearance the turbo (if your engine's a turbo) it should be the right level so you can use the stock pan. Guys who put the Subaru's into VW cars and busses don't have much wiggle room in positioning the engine, so the pan hangs down in those cars. In the 914 not so much.
