I had a similar problem on my '93 T100 4X4. The exhaust really
started to stink. One common cause of this on a vehicle this age is
the cat not getting hot enough. Since you've already had your rear
pipe fall off it suggests corrosion is rampant in the exhaust pipe.
Mine did the exact same thing. I replaced from cat back and still got
the smell. Upon further examination it was discovered that the flange
from the front downpipe connecting to the cat was almost completely
separated, allowing both hot exhaust gas to escape before passing
through the cat and cold external air to be drawn into the cat. The
combination of the two lowered the internal temp of the cat enough
under normal running to create that awful smell. Once I replaced the
front downpipe (no exhaust places around here would sleeve it) the
smell went away.
