Assuming you live in a foreign country...

== A THICK block plate between cylinder #1 and entrance to EGR cooler.

== A THICK block plate at intake manifold where egr pipe meets it.

== All cans gutted to the bare metal, insulation and all. Exhaust ad free-flowing as possible.

== Fuel line removed and blocked off at the IFSM for the Doser injector, as at some point in its future it will end up leaky from lack of use, and everyone blaming truck on lower then normal fuel mileage all the time.

== Any intake or exhaust butterfly valve(s) flapper removed.
