In general, when tapping an exaust system to pressurize a tank, you want
to place the tap where the velocity is lowest and therfore the pressure
is highest.  That's why folks usually recommend tapping a tuned pipe at
it's apex.

I've seen references to tapping the header mounting flange, but usually
that's for spraying smoke fluid in IMAC planes where the goal is to
get the fluid introduced into the exaust system early for max expansion
and in a hot spot.
