The outback is a legacy. No way an impreza skid plate will work.
Now if we're talking '03 outback sport, which is an impreza itself, then it might work, but I bet there's still at least a minor difference between turbo and non-turbo...
Even then, I know the '02/'03 WRX skid plate is significantly different than the '04+ WRX skid plate... the '02 is much shorter and includes the brake ducting trays... but that's probably not the same as the '02 outback sport undertray...
I'm getting the feeling it's a real crap-shoot on this one.
