How about you...
1. Get the car, then worry about the mods.
2. Find yourself a WRX specific forum, and they should have much more detailed information, because every model of car is different.
Not trying to be a **** here, but if you dont have the car (as your signature says), all these questions are completely irrelevant.

depends on how big the piping is... if the piping is too big you will lose horses

Bigger pipe = better on turbo
But its a different story on N/A.

as far as exhuast...
check gruppe-s for downpipes and up pipes. or even helix.
hks, blitz, greddy, and cobb have great exhuasts. i almost ended up w/ an STi, but got a SRT-4 instead
check clubwrx.net . very knowledgeable
Umm just so you know when you put bigger pipes on the Rex for example 3inch you will only lost low end torque(what a Rex is made for) but if you go with 2.5 inch piping you wont get the high rpm horsepower but a hell of alot more torque. And as previously said, wait until you are comfortable with the cars power before you add more. And a 3 inch turboback without a cat, has been said to add around 50 horsepower in the upper rpm range. First get a Helix up-pipe wont regret it, the turbo will spool faster because there isnt the cat blocking. Chief

www.clubwrx.net, www.wrxtuners.com, www.streetcarforums.com, www.nasioc.com, there are others but those are some of the better ones out there. How long until you pick up your Rex? And get rid of the tires once you get it. Chief

The up-pipe as you would call it,contains anywhere from 1.5-3x as much pressure as the MAP is seeing. So if you are running 10psi w/ 2x backpressure, the turbo would be then seeing 20psi of backpressure. There is a point where the backpressure actually equals the MAP, and the turbo itself becomes 100% efficient, but this only happens at around 40psi on select turbos on select cars...very rareOriginally Posted by norcalSRTrida
Which pipes do you refer? The up-pipe still needs to maintain some restriction to help the velocity.Originally Posted by jc25t
Thats why you keep the same size up-pipe, but just without the cat. Chief
