It is my impression that 2-stroke engines don't have oil filter.
So where do the metal filings (wear off from engine parts) go? Do they get
ejected out the exhaust?

If some steel part, like the needle bearing in the top of a rod, was
shedding metal, the engine would occasionally stop running when the
spark plug gap was bridged.
You might be mystified as to the source of the bridging and wonder if
you were maintaining your air filter properly. Then, one day, your
machine might quit in the middle of a race and you might wonder where
the rod bearing went when you tore the engine down.
Don't ask how I know this...

Bits of piston, ring, reed valve, power valve, yesterday's copy of the
Times - anything and evertthing gets chucked out of a stroker's exhaust.

If you blow them up thoroughly enough then bits will end up in the inlet
tract as well - when I killed my LC I found one circlip in the reed
block & the other in the spanny.

Only if they have an oil base. Most don't. 2 stroke Detroits have oil
filters.
