Congrats on the car. Welcome to the forums.

This subject has been covered MANY times. Most of it, especially exhausts, are subjective.

Please use the search function, and read the stickies at the top of every forum.

FMIC is bad until you upgrade the turbo, you will only be increasing your lag. BOV is useless and bad for your car unless your mods require it and you are tuned for it. CAI is the only intake, but still useless unless you are tuned for it. First place to start is a Downpipe and engine management for power, catback exhaust for sound.. if that's what you want.

Basically, save your money for a good exhaust-full TBE and engine management. Cobb AP or something similar. Then either go for a tune, you start buying all your parts, then tune the car. Many parts you cant even install on the STI until you are ready for a tune.

...and yes, search is your friend.

I agree with him on everything except the intake. I put a K&N Typhoon on mine at 5000 miles, and I felt positive results from it.

You would only want to change your BOV if your tuner tells you that you need to. Ever !

Good Luck, and welcome aboard ! And Merry Christmas ! Okey

First mod: Cobb accessport & Turbo back exhaust. Get a catted downpipe so that you do not run into boost creep issues, Many excellent exhausts out there its just personal preference.

I cant speak from experience.. yet. But I believe you are correct that you will feel results from an intake when you first put it on, then the computer relearns over time and puts you back to where you were before. Also IMO a short ram is pointless as you are only drawing hot air.

To get the full potential out of your intake, you are better off getting a tune for it. Otherwise you just spend $200+ for a new intake and gained about 2-3hp. IMO $200 is not worth it for 2-3hp, but it is worth it to me with some other parts. In my case intake/TBE/headers/solenoid/AP/tune.

Harmon Automotive just did a test and tuned for an intake and had some pretty decent gains, but only after the tune.

I went from 255 WHP to 290 WHP with a 3" turbo-back exhaust and AccessPort stage 2 93 octane ots map.

Later mods included cross-pipe and up-pipe, turbo inlet and lightweight crank pulley. After a custom tune I'm now at 320WHP and loving it!

Performance wise, IMO first mod should be either stage one or stage two. Please, do not even think about getting a bov.... Only get an intake if you are getting a protune. If you are just flashing stage two, and still want the "woosh" sound, removing the intake silencer - there is a how-to somewhere on here about that. Good luck and welcome to the forums
