Paul, the distance the muffler  stands off from the block, measured on
the muffler centerline (closest point),  can vary from about one inch
to  two inches.  Moving the muffler in or out may help resolve some
conflicts.     Also, the exhaust pipe can be turned 90 degrees so the
4
inch flat is perpendicular to the long axis of the muffler.    Jerry

Yes I agree but you will play hell coming straight out the bottom with
most  motor mounts.

Just to confuse the issue here is a 90 degree rotation transition from
fore and aft
to side to side. Probably a little quieter and a little bit less drag.

That's cool.  Looks like one could build a hundred  versions of this
exhaust system  and not repeat  himself.   I plan to start out simple
and establish a base line for power  and sound.  Then test different
configurations.    When are you going to have an engine on the dyno?
When  you do, will it be a situation were we can test different
components?     Jerry

Here is the flat patterns for that muffler Jerry.

Best to mock it up in cardboard and tape it together to see which part 
is bent which way.
