Well after a failed attempt at trying to remove my old headers and up pipe I booked it into GT Developments.
And after a day of grinding, heating and swearing the old bits came off and the new equal length headers and up pipe went on.
Found out that the manifold has a slight manufacturing problem and is causing it to blow a bit on passenger side head. So some new gaskets are on there way from Subaru.
It will be seated out front of the JDesigns stand, hopefully rip out more weight if I have time
