Description
Each engine cylinder has a separate exhaust pipe routed
down merging in the left or right collector tube with increasing
diameter. Several exhaust pipes feature slip joints to allow
for thermal expansion.
Two end pipes protrude through the lower engine cowling for
exhaust gas discharge to the atmosphere.
Operation
The exhaust pipes are of welded Inconel 625. These pipes are
routed from the cylinders down to the collector pipes under
the engine.
