also.. how could the muffler have been causing a knocking noise?

If any of the hangars are loose or broken the exhaust will be loose, and when it is loose, it can bump into stuff.

Did you do like I suggested and give it a shake?

Here is how I check the diff nose mount. Stick the pry bar in, push up on the handle. If the mount is torn, you’ll see it separate.

Mine was broken (the rubber) and as a cheap repair i once welded a u type of metal under it with a fat piece of rubber in between... HAHAHA after 10 years it's still on there !!!  😂

Sometimes it’s hard to see if they are cracked through. Not sure if aftermarket quality… I used OEM.
