Anyone know how to make a spark arrestor for a YZ silencer?

My questions is- has anyone ever made a spark arrestor? It appears that all I need to do is drill out the rivets on the silencer, and insert a conical shaped heavy duty metal screen into the end, push the cap back on, and screw it all down tight.
Has anyone ever done this or made their own spark arrestor another way?
I’d appreciate any suggestions on this,

Although I've never been stopped while riding in a national forest, from my enduro days i remember that the forest ranger will try to poke a stick down the exhaust before the race. If it goes in a certain distance, you obviously dont have the spark arrestor in place and they wont let you race.
It seems to me that they dont go looking for any sort of visible stamp on the exhaust system, but rely on the "stick test" I mentioned. I could be wrong, but it seems that as long as there is a screen of some sort (with a large enough mesh to minimally restrict airflow), then thats all they're worried about.
Is this not correct?
