Were you able to preserve the iconel(?) stubs and slip joints where the 
3 ports exit the cast plate? I'd bet the slip joints are essential to 
the system working correctly and surviving.

Looks like you found the one at the exit bend. :-)

I tried to use the flywheel end exit to advantage on mine; my pipe goes 
down/aft to an Aeroturbine muffler I managed to keep within the cowl. 
Not yet flying, so can't comment on reliability/success.
