    Electric exhaust cutouts?

    I'm looking at electric exhaust cutouts for my wrx. Anyone know of a reliable brand? Heard people have had issues with a few out there. Thanks.

    Curious about this... would you want a tune for open versus closed?

    What model year?

    Just wondering what benefits you think you'll see from an exhaust cut-out. Not really anything is to be expected from that, especially if you already have a full Perrin exhaust.

    Ya, it's more for fun. But I've heard up to 11hp, and 9tq gain. Just trying to find out which brand to go with.

    False. I'm assuming you plan to install this in the midpipe? Then it's essentially just a muffler delete. That said, since you've already got the Perrin catback (which is already fairly loud, IMO), I'm not sure it would even make that much difference noise-wise, let alone any sort of performance improvement. Personally, the results wouldn't justify the effort if I were in your shoes, but to each their own.

    How did you get an STI intercooler to work? The TBs are in different locations.

    It's not that hard. You just have to get creative with some extra silicon I/C hoses. Zach had an STI intercooler installed which I now have.

    Actually found a shop that will tuck it up on the down pipe, to remove any ground clearance issues. And it's actually pretty incredible how loud it becomes. The only problem is finding a reliable brand.

    Yes but it's a lot different on the GRs.

    In an 09 it is...the turbo is located/mounted differently and the Intercooler/manifold and such are completely different styles. The WRX is more of the Legacy GT style, where as the STI remains similar to 02-07 WRX/04+ STI style, like your car's layout. So you can do STI intercooler and turbo swaps all you want in the GDs, but not so much in the GRs.

    Very curious to see how OP had that done...

    All the OP needs is the STi intake manifold. The question now is, WHY?!! The VF52 has similar potential to the VF48 and for the price of the STi intake manifold, the OP could have a much better TMIC. Pretty ridiculous modification IMO.
