I wonder how this happens? Hole on the top of the tail pipe, not where the breather exits... We've always said that we were trying our best to wear it out. We seem to be succeeding. The prop is off for some TLC this week too.
Looks like typical thermal erosion failure to me. Pretty typical for the stainless alloy used for light aircraft exhaust. How many hours on the exhaust?
