You won't be able to find a replacement heat shield for the cat. They are spot welded on. My bottom one is gone and my top one is held on by muffler strapping.

As for the manifold heat shield, mine has now been off for years. I'll still get one if I come across it in a junk yard but I'm not seeking it out. Plus like I said above, the bottom bolt is still on the manifold do it will be quite difficult to install anyway.

Good luck

 

Okay!! I was thinking that Honda Civic is a Honda brand so I can easily get replacement or any automotive parts from here. Thanks for helping me out. For sure I will check it out local yards. Will it be helpful!
