After Bob has the lower cowl fitted, have him mark the exhaust pipe
where the outside surface of the cowl meets it (well, for heat
reasons the cowl most likely won't actually *touch*, but you
understand my drift).  Then make a roughly 35 degree cut across the
exhaust such that the cut piece can be rotated 180 degrees and
re-welded.  Voila', a backward-pointing exhaust pipe.  Blasting
exhaust straight out from the cowl is draggy.  For the
imaginationally impaired, the end result will look like the square
exhaust pipe has a dog leg in it.

Hi Russell,

I'm thinking of just cutting it off at an angle (long part in front).
Maybe about 4-5 inches beyond the cowl.  I have an antenna right behind
there which I'm hoping I won't melt, but wouldn't want to point the hot
gasses at it.  I may have to move the antenna.  I could weld a short
section back on at that angle if it seems necessary.
