Indeed.  The differential venting caused by the wastegate on the stock
one-piece manifold has often interested me, but I've never had time to
do anything serious about it.

I've never seen a one-piece manifold cracked in only one place.  Every
one I've seen has been cracked in two places, and it's always the same
two places.  The configuration and loads on the thing make me happy
that the front crack is a direct and immediate result of engine mount
failure - but I wonder on occasons about the back one.
