    What kind of hp could I expect with the following mods?

    First off, I wasn't really sure where to post this so I posted it here, sorry if it is in the wrong area.

    anyways

    05 sti
    HKS Hi-Power Exhaust
    HKS SSQV Bov
    K&N SRI
    HKS Down pipe

    So what kind of HP and torque numbers could I expect after a tune on 91 octane gas? How much of an increase would there be if a HKS Up pipe was added?

    The HKS downpipe is not a good model. It's pretty restrictive. I'd opt for a bellmouth downpipe.

    And the SSQV doesn't belong either.

    Sorry I don't follow. Do you own the 05 STi you described initially, or are you trying to buy it?

    correct, btw i already read the thing about not buying cars with mods but i know a bunch of people that can verify that the car was very well taken care of and for the price i can't find anything better, it is being sold for 15.5k with 64k miles and a clean title with no accidents

    You guys are better than me for continuing to entertain these questions. If he had only a few posts then maybe, but he's been here long enough to know IMO. Good luck.

    I was inferring that since you do have 60 posts you've obviously been here long enough to know why Donkey said what he said. Do some more searching/reading on what you're asking before you post. You would've found out that the HKS DP is really restrictive, as mentioned before. And the UP on an STi is already catless, so there's really no reason to replace it unless the car has a ton of miles on it or you're adding an EWG. Don't forget about EM too. Good luck with finding your new Subaru.

    I'm cutting him slack because he doesn't actually have a Subaru at the moment so I doubt he's done researching we'd expect of owners.

    Like I said, you're a better man.
