Had some Borla header collector mufflers ceramic coated to match the headers and they came back with what looks like a fine sand in the packing of the muffler. I have blown a lot of it out but I can hear more in there when I tilt them up and down. I am worried that if I install them sand will fall back into the engine when it is not running. The guy at Borla thinks it will be OK but I am not so sure. I have the regular slip on collector on it now.

Sounds like they did not plug the openings when they ran them through the polishing media. After they are coated they have a finish that looks like natural aluminum, then the parts go in a large vibrator filled with various sized ceramic beads, it is those beads that bring the shine to the finish. As a side note on the finish, there are a couple different companies making polish specifically for ceramic coated headers, save your money, I tried some and they seem to have too agressive of a compound, and leave marks, get some Mothers Billet polish. Great shine, and each time you do them, they get better. Was at CFW over the weekend and someone commented that those look like chrome.

The polishing, if you have TRUE ceramic coating and not just a "jet hot" type coating, is done WET. And the polishing media is way too big to fit thru the screen of the muffler. Can you imagine the amount of water one of those would hold. And even though the packing is SS, it would be trashed and compacted in tumbled while full of water.
My guess is, the sand blasted them and didn't bother to cover the ends.

So you think the stuff is going to climb the near verticle back side of the muffler and get in your header tubes, and opposed to out the slope end of the muffler and out.
Are you nearly as concerned that the packing will be ingested by your engine too?

Despite all the air I have blown through it with my air compessor if I shake the muffler sand comes out. My worry is I will be towing the boat down the road on the trailer and they will shake. As they are OT headers the sand will go downward into the engine. I like the idea about the leaf blower and the mallet, I will have to try that. I will probably end up doing all that I can with copressed air until I can't hear sand in it anymore. As I rotate it top to bottom you can hear sand move. What a pain
