Paul,
    Attached are the cad drawings for a fairly simple bracket (two pieces,
rectangular tube and stainless steel strap)  to attach a exhaust tube or
muffler to the fuselage.  I ended up only using two bolts on each bracket
and made the bracket somewhat shorter.  It is for a 2" dia pipe/tube but a
similar approach could be taken with different size tubes although a
different size rectangular tube may be required to accommodate large tubes.

    Plate nuts are attached to reinforced plates inside fuselage and
provides a secure anchor for the pipes.  No, I did not use the rubber
muffler donuts I show on the drawing, which I had as it would have cut down
some on the vibration transmitted to the fuselage.
