where can i find...Headers, Test pipes/racing pipes, short ram intake, exhaust....will any parts formt he WRX and or STi work for me?

im sure parts from older models will fit perfectly with the 2005. As far as wrx parts.. most suspension mods will work, exterior parts, axel backs, pullys. most engine parts will not work, nor will a front sway bar or anything which says its made for a turbo (mid pipes etc etc)

www.cobbtuning.com is a great site
www.boxer4sport.com its got some good stuff - i got my stromung mid pipe from them

exhaust, you have many options to play with
intake, a lot of people like the cobb cold air
headers, borla and some other companies out there

from what I hear an amazing mod is cams!

Welcome to the board! Please don't forget to read the FAQ's in the General Forum by Unabomber about general performance information to get you started. And don't forget about the trusty search button to help you on the way.

Parts designed for 2000+ 2.5RS's should work on the 2005. Good luck.

EDIT: Snaps, I just realized that you are running MAF. Don't know how that'll change things up.

I know you have more cats, try to put on a header/mid pipe from a 2004 2.5RS. I wish I had your AVCS.

Ok, thats alot of mis-information in one sentance!!!

1) The 2005 does not have more cats, unless you have one of the PZEV 2.5's on the Legacy.

2) There is no AVCS on the 2005 motor, just a new redesigned intake manifold and electronic throttle.

^^ Redesign = Better performance? or Cheaper cost?

Sorry I was under the impresion that all 05 2.5 n/a were pzev. That could be wrong. However i read in autoweek there is or will be the pzev motor in the impreza. I thought it had avcs aswell.
