I couldn't find where anybody else was talking about up pipe swaps, but has anybody considered/done this already? I was looking at the Invidia up pipe and wanted to get some opinions.

I have a Perrin up pipe. The thing is you don't really need it on the 08 because unlike the previous years there is no CAT in it. There is a sleeve inside which makes the pipe a bit smaller but nothing too drastic. I'm not saying don't do it but if you were gonna pay someone else to install then I would say not worth it. If you can DIY do it for sure. :)

Slightly yes and throttle response was better. It wasn't a night & day difference. It does help when you do have TBE thought I will say that.

i have a Perrin UpPipe. I recommend doing this if you are going to upgrade the turbo or install headers.

Quite a PITA just like all the other WRXs to install.
