    Fewest mods for 300whp

    Just a quick one.

    I am just pre planning some mod ideas for a 2009 WRX. It is one of the cars I am looking at getting and would like to see what I am expecting to have to put into it parts and cash wise.

    I don't want to have to raise the boost to crazy levels, but a small increase will be fine. I don't want to do any turbo mods. And I would like the engine bay to look as stock as possible.

    What I have been looking at has been equal length headers. De-Cat and full exhaust system, doing the up/down pipes. Intake. And of course having it tuned.
    But has anybody done just these few mods. And what sort of gains did you get. I also know better brands will give better performance and reliability. I am just looking at this from an on average point of view. For products in the middle of the range perhaps.

    I plan on hitting 300hp at the wheels. So with these mods will I make it, if not then what else would I need. I don't really want to go to much over 300whp, since I want the car to be as reliable as possible. And I don't want to have to uprate all the brakes and engine mounts or whatever.

    Thanks guys.

    DP & a tune will both be cheaper AND yield better power results. A tune and CBE will cost more (includes mid pipe) and not give the best results. The DP is a larger factor. A CBE is more for sound. You can get a tune and change NOTHING and get some decent increases if you want to stay on a tighter budget for now. Just keep in mind you'll need another tune if you later decide to change the DP.

    Zax and jaysin said the answers. Don't pretend like you're going to stop there though. That's what we all said. Now I'm sitting on aftermarket intake full tback full suspension, shifter, wheels tires, and waiting on my parts for e85 to ship lol.
