Broken RHS exhaust manifold

[aSTerix]

I am trying to compare my physical exhaust manifold with the diagram to work out if I just need a new gasket or need to replace the manifold, can anyone help based on the photos ? Or does anyone have a photo of a perfect RHS manifold I can compare with, thx

If you remove the gasket from the tube you will see the piece that has broken off.
You could weld something in its place or replace the header pipe.
Delkevic makes a good replacement. you could replace the entire header and re-use the original mufflers or you can get the whole system. I find the Delkevic muffler a little too loud for my taste although they aren't overly loud.

Is there another piece that extends the manifold further , I checked in the gasket and didn't see a tube ?

I have found someone who says they can TIG weld a new tube piece, I just need to get the length right !

if anyone has a RHS manifold on the bench could you possibly post a photo of the end part that takes the gasket, that would be hugely beneficial

Found it ! well what was left of it, there is enough there though for me to work out the length of new tube required. I will also do a bit of measuring on the engine to check the longitudnal alignment of left and right exhaust ports and can figure that into the calculation

Edit: I measured the longitudinal alignment and the RHS exhaust ports are approx 18mm (11/16") further forward than the LHS

Just in case someone looks at this thread in the future, here are some photos I found showing what the RHS manifold should look like
