This is what the federal post oxy trap replacement looks like. The pipe
to the front is for the EGR. Everything else feeds the trubo directly.
If it didn't, it would take forever to spool.
1bar is about right (11.5PSI is generally the right number for the mb
diesels).

Sweet. So all the exhaust is supposed to go right into the turbo.
Interesting. The plumbing on the USA version like mine looks like the
exhaust goes partly into the EGR, which makes sense (from the EPA's
point of view, I mean)---partly into the turbo, which makes sense---
and partly straight out into the cat, which doesn't make sense to me
(why waste exhaust gases that potentially could spin the turbo
harder)?
The diesel turbos don't provide a lot of boost IIRC, about 1 atmosphere?
Spinning the turbo harder would produce more boost than needed and maybe
increase exhaust backpressure vs. just venting straight out.
