WR1 Up & Down Pipe onto a MY05 WRX?

[D-an-W]

Hi folks, I am in the process of preparing my MY05 WRX (Inc PPP) for a remap and have the chance of a WR1 Up & Down pipe.

What I would like to know is are these a straight swap (Other than removing a chunk of metal from turbo end of down pipe) and does the WR1 come fitted with the same Decat Up Pipe with heatshield and Prodrive "Sports Cat" downpipe as the STi?
Also is the main Decat pipe after the down pipe the same as a WRX or should I get that section too (It's a Blitz NUR Spec R after that pipe)?

STi Up Pipe (AFAIK)...


STi Down Pipe (AFAIK)...


If anyone could show me pictures of actual WR1 exhausts that would be a great help and of course any advice offered is much appreciated.
