RE; exhaust going?
I just repaired this on my '87 5kSQ and have seen it happen on two
other 5k's. The leak is probably from the compression joint between
the catalytic converter and the pipe going back. The three bolts
holding this joint together rust away to nothing. The fix is to
remove whats left of the old bolts by cutting or burn out with a
torch, replace the $4 gasket that is in between the flanges, and fit
new stainless steel bolts, nuts, and lock washers. <$10 in parts and
about 1/2 hour labor. Much easier if done on a lift and its one the
few Audi repairs that any gas station mechanic could do with minimal
supervision. Just make they don't bang on the whole assembly too much
while getting the old bolts out or it could damage the manifold. If
your ambitious there is a similar joint at the front of the catalytic
converter to the downpipe that could use new hardware too but this
seems to last much longer than the rear joint.

Subject: exhaust going?
I've recently detected a much 'sportier' sound coming from my 885ksq
sounds like the beginnings of an exhaust leak, but I haven't been able
find it yet. Seems to go away after warm up. Just wondering if there
well-known exhaust manifold failure mode on the NA 5Ks, or anything
should be looking for...
