Im just trying to get things straight cause I might be interested.....but this is am oem manifold that has been ported and polished by gs? Or is it there manifold too?
I assume the porting on it is equivilant to throwing on an aftermarket header?

That's correct. For $230, Grimmspeed will port and polish your factory exhaust manifold. For another $180 you can add a high flow crosspipe with a flex pipe on it.
The total for this setup from GrimmSpeed right now is 450.98, because it also includes an EGT tap.
This is very useful, especially here in CA, because you can put on the factory heatshields and go get the car smogged without header swapping. No, it's not THAT difficult, but for my DD I don't want to deal with it but I still want the performance.
I'm selling because it doesn't fit my Legacy GT.

Whoever got this is gonna be stoked. I have a similar set up from Crucial and it's awesome. Totally stock appearance but it does make a noticeable difference. I love mine.
If I didn't already have one I would have scooped this one up.
