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.

    If you open it, you’ll find peanut butter.

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

  9. Meshooo says:

    thanks h2o, u must be a fellow employee in the oil sector…KOC here

  10. Meshoo i think you work for an oil company or oilfield services :)

    Inside, little machine elves chew muffle your sparks with their bellies.

    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.

    no vehicle enters an oil refinery without it
