The thing with turbocharged cars is that you don't have to open up the exhaust. Although, it does help. Getting cold air to the turbo, and cooling it off after it's charged(intercooler,) can make a huge difference.
I've never worked on a Subaru, but if you can add boost and fuel, you can add 75hp...the problem is. On most OBDII cars, you can add intake and exhaust stuff, but without being able to scan the computer and change the programming, it isn't going to do much.
