Thats the problem the wing is right where you are trying to run the
exhaust. That spar is covered by the wing, there is no space there.

I think we are not talking about the same part. The spar is inline with
the
fire wall on most pushers so it is well ahead of the engine and well ahead
of
where the exhaust pipes come out of the engine. The drawing is to scale.
Now there is cowling there and that may be needed to be made from
metal around the exhaust pipes.

In this picture of Tom Jordans airplane you can see the muffler fairly
close in to the engine. You can also make out the burn parts on the prop.
The spar is inline with the firewall and well ahead of the muffler.

Yes but, I'm talking about the wing to the left of the muffler, You can not
run the muffler any closer then he has it now. the ailerons bellcranks and
all the control cables are in that wing root.

Well I guess you will just have to go to a metal prop if you don't want to
move things out of the way.
