Exhaust line heat shield

Hey everyone!

I got a question for ya'll!

The other day while driving, I started to hear a pretty annoying rattle from beneath my car. After some investigation, it turned out to be the hear shield.

It seems that my heat shield had started to fall apart or become loose.

My question to all of you is.... is the heat shield something I should replace? Does replacing it add any value or can I just rip it off and leave it off?

Please let me know your thoughts.

Thanks!
