More info when I have it.

In the mean time, be sure to do a thorough exhaust system inspection during each condition inspection in accordance with AC43.13 Appendix D.
Scott,
Was there an outcome from the investigation with engineering?

Thanks.

I think one of the guys on the sustaining engineering team is working on this project now.

I checked mine when I first heard of the problem earlier this year but found no wear.

At the last annual however, two months ago, I found that the circular ends of the forward muff had cracked and needed to be replaced. I ordered new parts, including enough to do the rear muff.

The parts were backordered at the time, but they shipped about a month ago. When I rebuilt the muffs, I found no wear on the exhaust. It is on my list of items to check whenever the lower cowl is off.

450 hours on the old ones with no wear. We'll see how the new ones hold up.

I am installing the sleeves and I made a slider in one of the holes so that when I tightened them with the clamp it fits more

Just make Rick Robbins the supplier to Vans for the end plates.

This is the correct answer. The Vans muffs are mis-engineered and should not be installed. Mine failed under 100 hours. I believe he used to be the supplier before they were brought in house.
