Ashley 16v conversion manifold...

I've got an ashley manifold on my 16v conversion, its the 4-1 2 peice manifold, but im missing the second part that connects to the system. Seems the person who fitted the last system did a bit of a bodge job, but didnt use the second part of the manifold.
So now i'm having problems looking for a system to replace mine with, as I don't have the second part, the system wont connect to the manifold. Does anyone have any suggestions, aside from getting one custom fab'd?
I took it to a couple of local exhaust places yeasterday, but they were WORSE than useless. They insisted the car is an import…which it isn't, so couldn't help.

I was looking at this CLICKY But have no idea what the quality is like, whether it will mate up, or even be the right bore. The bore of the manifold pipe is 2 1/4" (from my measurement, may be wrong)

Starting to tear my hair out over this D:

Just buy the whole thing from Ashley.

I did have a look at the Ashley systems, but they are just out of my price range. Super poor at the moment and the sportex system is the only thing I could find within my budget.
