does diesel soot clog mufflers?

They sure do clog up

In fact most diesel owners will notice that after driving around the city for a while, the first big rev up hill or overtaking, they start blowing irregular puffs of black smoke/soot. Those puffs come from soot stored in the mufflers and bends where gas slows down.
Soot is a powder, as long as you do some long trips every now and then and your diesel is not overfueled you should be OK.
To clean it up, some buses used to have plug where water could be inserted to clean it up but that is no longer considered environmentally friendly as all the black water ends up somewhere...

And you will find that the mufflers become heavier after a few years with the build up of soot.

So changing them every 10 years is not a bad idea.

Muffler?? whats this muffler you speak of ??

LMAO!!

dont forget the carbon absorbs water vapour and sulfur......if you do short trips you can rust a good muffler out in 3-5 years
