Diesel engine parts for post-treatment of diesel engine gas exhaust

TL;DR

Try to find parts from post-treatment of diesel engine gas

Hi folks,

Any idea about what is it?
I am required to find parts like these items which are made of stainless steel 304 and used on the post-treatment of diesel engine gas.

They look like flexible gaskets. But, my best guess is that it is a spark arrestor. When a diesel engine is working too hard, strands of carbon blown out through the exhaust, are hot enough to re-ignite when they reach the air and start fires in dry vegetation.
The braided wire would work like a HEPA filter to catch large particles. They would be held in the wire tangle until excess oxygen is available to burn the carbon, so the filter is self cleaning.

Braided wire works as a flame trap in gasoline vehicles because the wire cools the flame front.
