    Can I ask why the big tube headers? Are you planning on changing out the turbo, or leaving it stock? And did I miss an uppipe on the list?

    I installed the perrin headers with the stock UP, and recorded a difference (albeit small) when I did the uppipe later on (could be been dyno differences, but it was on the extreme side of that). Your mileage may vary.

    I have a 2011 wrx. I set out to spend the least money on a daily driven setup. I have a PW TMIC, Cobb DP, ID 1000's, DW65c, Grimmspeed EBCS and Cobb AP. I protuned on 91 and E85. On my high boost map I put down 301/335 at 6,000 ft altitude. The only thing I would have changed (am changing) is a better BPV. A turbosmart recirc BPV is otw now, as mine failed at Friday night drags lol. But I run 13.2 at altitude (7000+ baro) which is pretty fun. Setup cost about $4k including tunes. Don't waste money on an intake unless u plan on exceeding the 425+ stock airbox rating. I put a k&n drop in before tune. My setup maxes out the VF52, so unless u are planning for a bigger turbo u really don't need anything else.

    An intake is worth it on S2 VF cars, especially if you have injectors.

    I'd expect 10-15whp peak increase out of an intake on those setups, with more towards redline (especially with enough injector headroom).

    Different flow characteristics? It was my tuners opinion that I was maxing stock turbo (safely for dd of course) w/o intake. High boost setup was 20.4-21psi peak. From Harvey at the boost creep. Again, not tryin to disprove. I would be happy to learn that I could make more power.

    To clarify (on the reliability point of view), I run the low or mid boost map (15/18peak) daily. The high boost setting (show off map ) is for cool nights and the track. Harvey warned me that using the high boost setting too often will risk the safety of the turbo. I respect his judgement and all is well so far.

    E85 is way safer. On low boost of course. My tuner made me 3 maps for e85. It's roughly 110 octane.

    The current Legacy GT-style intake used on the 2009+ WRX is shown to be restrictive even at stock power levels.
