Well if you have a few hours, just take it off and find out, I'd imagine that the results are similiar between the wrx and the STi. I did it to my wrx, no need to do it to the STi just yet

The engine/exhaust is a little more pronounced, and you can hear the recirculating valve go. I believe when i did it the turbo spooled up 200-400 rpms or so quicker.

Any actual power gain was not discernable by buttdyno.
Few hours??? It took me less than 15 minutes and I'm not mechanically inclined at all. I think it's worth it so you can hear the turbo and stock bov a lot better. I don't see any major downsides, unless you submerge the car in deep water.

If you check out, they tell you exactly what to do and what tools to use. It's worth a try since it's so quick and easy to do. If you don't like it put it back on.
