During my preflight I grab the exhaust extension below the cowl exit and give it a good shake.
At 16 hours into Phase I, my right pipe was loose.
Looking into the cowl exit with a flashlight showed a broken exhaust hanger.
My hangers are connected to the engine sump so the exhaust moves with the engine.
I called Clint at Vetterman Exhaust and he said the hanger tubes can break if they are bent for fitting during installation.
As can be seen in the pics, mine is not bent.
Clint also said they have had some rare breaks for unknown reasons, perhaps a defect in the crimped end.
I think I will move the cross piece up a bit to make sure it does not rub on the nose gear mount.
Anyway, I replaced the hanger tube and will continue checking them during preflight.
Just wanted to give a heads up to all about checking those exhaust hangers.
I put the hanger back together for this picture.....
