I'm new on this site. Just got my first 06 wrx.
It's still all stock but not for long
There are couple of things I want to do but dont want to spend all my $$$ on mods.
Injen intake system - costs around $280 and add 20hp ( is that true???)
And of course cat back exhaust for better sound.
Is there any cheap and good stuff I can use?
No downpipe or catless, just cat back for now.
