Here are two photos of the ST exhaust system for Bob White's BD-4.
Every system is unique, as engine mounts and cooling packages are

the cowl is fitted.  Jerry

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.
