3) The VAM muffler *almost* fit.  The exhaust pipe hits one of the mount

tubes, preventing the exhaust manifold flange from seating against the

engine correctly.  There seem to be 3 possible solutions:

   A) Make an insert for the manifold flange which adds appx 1/4".  Not

convinced the bolts are long enough for this.

   B) Cut the exhaust manifold pipes & lengthen them so the VAM moves

1/4" - 3/8" farther away.

   C) Cut the VAM exhaust tube & increase the angle toward aft so it

clears tube.

Mark,   When I built the muffler, I did it with the engine mount in
place.  I had it off and on many times.  It had to be angled just so to
slip it over the flange studs, but it did fit. I have no ideal why it
would not fit now.  Of your proposed solutions, the last one would be
easy to do. Cut through three sides of the exhaust so the last side can
act as a hinge. (It can be cut on a band saw or with a plasma) Heat
with a torch and pull it the position  you want.  I can send   you some
321 strips for the patch and also some 347 tig rod (required to weld
321).   Or, you can patch it with 304, readily available everywhere.  To
weld 304 to 321, use 309 rod.

I am very disappointed that you are having difficulties,
