And to further explain so others don't think I'm totally nuts    .....  ha ha

One of the big hurdles for me as a total newb to engine conversions
was getting any kind of exhaust up and running even just for short
test runs; I knew enough then to know that the joint between downpipe
and flange at manifold needed to be 100% good. With a "factory" made
downpipe, one might stand a better chance of at least cobbling
together an exhaust to allow a trip to the local exhaust shop.

The first welds to fail were at the joint from exhaust downpipe flange
to downpipe. Ironically, these were done by a pro fabrication shop.
BUT.... these happened after these cracks showed started. Image of V
1.0  cracks near pro welds:  http://tinyurl.com/la6kgzh  It was
obvious that the issue wasn't the weld quality but my design and work.
