Klaus, you make a good point. I did tighten one side more than the other. I'll see what I can do about the angle, but I think it will be still be askew.

I need to investigate the flexi-issue a bit more. The hangars are in excellent shape all the way around. I have clear photos of each (didn't feel like uploading them) and I've tested each for dry-rot.

The way the pipe "moved" felt far too easy. ...like I was lifting up one end of a short 2x4 off the top of a pile of lumber. I would have expected more resistance if the pivot point was on the muffler and I was fighting resistance from the cat-to-muffler clamp. However, there could be a problem farther forward.

Here is the rear pipe junction. Maybe I'm imagining it, but the area around the junction looks as though it's been physically stressed. The white stuff is also peculiar.


Like I said, I need to investigate this further. if it really is broken here, I'm not sure if this can be fixed. Then again, it might be fine.

I'm still getting a lot of exhaust noise, but isolating this pipe has made a difference.
