^^ Wow, you aren't running an 02's, my local tuner told me it's critical to have at least one of the 02's working, I can't remember for what but he said it was important. I wish I could remember if it was front or the rear but when I asked him to remove the 02 codes, he wouldn't do it as he told me it has to do with fueling or something along those lines.

Yeah, the way flightwatch is doing it is NOT a good idea. The ECU is unhappy and using its failsafe tables. He's also going to have less control over AFR and will require retunes every time his gas station changes blends (which happens twice a year, minimum). No O2 sensors is not a good idea for a street-driven car.

Keep in mind not everyone gets the CEL. I had my UELs in -30 winters, and not a single check engine light...

The 2.5i' seem to be more sensitive to the UEL's and please understand the ECU's are not the same on 05 and earlier and the 06/07s. You can not use certain fixes on 06/07's that you can on prior years. Like spacers, of the resistor fix, etc etc.

You got the year split wrong.

The picky cars are 05 and newer, the easy to please cars are 04 and older (they get easier as they get older).

Gotta love 2006+ N/A manifold design engineers damn them

I'm still trying to figure out what to do if I get headers and a catback. Will any 08+ wrx downpipe work to connect them because I know some people use the stock downpipe from an 04-05.

No, the 08+ downpipe will not work for you. No, no one used an unmodified older downpipe either.

Some people have used, on older cars, the turbo manifolds, crossover pipe, and then a custom pipe that replaces the up-pipe and the vertical part of the down-pipe, before tying into a turbo cat back.
