Exhaust hose reducer

In all seriousness I am interested to know how it is done in a wet exhaust. It is a simple matter with a modern automotive engine but I can imagine it would be a PITA with a wet exhaust with no convenient bung hole, not to mention bad for the gauge.
 
From our Beta installation handbook:
"Back pressure should be measured with the complete exhaust system connected and the engine running at full speed. The correct measuring point is before the injection bend (at the manifold flange). We can supply a Manometer kit for testing back pressure."

So it's a spacer with a take off to go between the manifold and the head then?

Haven't found that within the several docs that accompanied the enjin. Must ask the Beta owner/director tomorrow, when chasing up about the other three unanswered queries....
