New manifold designed, manufactured and installed
OK, I know what you were thinking and I tricked you to read this. It is a vacuum manifold. 
There are a few reasons that I went through the hassle namely:
1) Slightly cleaner vacuum line routing
2) Slightly easier debugging in case of a vacuum leak, since each line has a specific function and affects the others minimally.
3) Quicker response time for FPR (should give slightly better throttle response), for BOV (less stress on high pressure intake hoses and joints) and for boost activated water injection (particular to my case). Remember that each device to be activated has a canister with a certain air volume that needs to be evacuated and by running all of them through a single thin vacuum line (for part of the path) will slow the actuation down.
The KLR maintains its own banjo fitting.
Porsche apparently also saw an advantage in this by giving the Turbo S models an extra (small) banjo bolt for the FPR.
The first picture is the (brass) manifold by itself and the second picture shows it installed with vacuum lines attached.

Looks very good 
Any more details on it (in terms of production, costs etc)
BTW, this would require some minor re-routing of the vacuum system correct?

Uhm.. Pink intake manifold.. Why?
(Your <i>other</i> manifold is quite neat.. I think I'd buy one if it were reasonably priced, or at least be interested in how to make one!)

That looks great, any idea what it would cost to produce? I am re-doing all my vacuum lines over winter and that would simplify it much more. Also if you produced it is it possible to be anodized?

I am in!!! make sure the air flow is propper so it can produce strong suction ...you might want to run onlu 4 ports nicely spaced inbetween each other so none interfear with each others flow/suction and man you have a beter idea than tapping little bajos in the manifold!! good work
