Tom : There's no reason that you can't do a repair like Stu did.
You might use some 5 minute epoxy which sets up much faster than the Marine Tex. That way you can build it up with a few layers and then use Marine Tex as the final. Just make sure to you don't increase the diameter too much larger than 1 5/8" and that tube is smooth and symmetrical when you're finished.
If you don't have a single hump hose now is the time to install one.
The hump hose takes up the vertical shock so that tube on the inlet of the muffler doesn't take the shock. A few thoughts.
