What is this?

unknown object

I see these muffler extensions every now on then on cars and I have no clue what they are. What do these extensions do?

Update:
Here is the answer given by Meshoo

They are called spark arresters, some cars have them built in the mufflers, but some don’t, it is a safety requirement (though an ugly one) for these cars to be able to enter the oil fields…because some oil/gas production facilities might have a leak that may cause a fire or an explosion if a car does not have such an attachment and cruises near by a facility.

Spark Arrester like Meshooo said, its required by oil companies KOC, Texaco, etc.. if the vehicle is operating in their sites.

Meshooo is correct.

All Oil field Employee’s/Contractor’s Vehicles must be fitted with a spark arrestor like this.
It comes with different sizes to match with your exhaust pipe.

Attn SWOS: (please note the point)

The approved Brand name is “Nelson” and it is available with companies like M/s Fares Al Dabbous, M/s Arabi Enertech etc,

Some cars already have this installed like the Toyota Camrys last yr and therefor were exempt from KOC/JO requirement. Oilfield here too.
