As received from Great Plains.  I
cut each 90 U in half.  Also
included are mounting flanges.
Each tube was tacked on the
engine with a wire feed welder.  
They were then removed, the
inside fully welded, and...
The outside fully welded.  I will
coat these in a high temp
coating as soon as I decide on
one.
Exhaust pipes on the engine.  I
decided to keep this build
simple.  I wanted to build
custom 2-1 or even 4-1 pipes,
but that will have to wait.  

There are some things I plan on
doing in the future after I have
some experience in the aircraft.
