Thought my engine was sounding a little clacky at idle, and not quite right. So decided to
drop the exhaust to check the gaskets, and flanges. Glad I did, found a cracked pipe on
CoPilot side rear (covered by the clamp strap), and a broken Flange on Pilot side rear

None of this was noticeable until I unbolted it and it quite literally fell apart ...

Might be a good idea to add "Drop and Inspect Exhaust" to your IO-240B Annual ... None
of these breaks were noticeable with the exhaust mounted.

Here's a scary break, that was completely invisible before disassembly

Notice the Break is completely covered by the strap.

This flange looked fine, but fell into two pieces when the nuts were removed.

Can see the weld on all these flanges does not completely encircle
