Catalytic converter heat shield noise
To my fellow 2004 frontier owners, have you ever experienced the catalytic converter heat shield making noises under your truck whenever your truck is on a stand still? Well I have that problem. I just want your opinion if you had experience that problem before to whether change the heat shield itself? or replace the whole catalytic converter? Thank you.
Are all the bolts tight? Is it bent in any way?

That, I'm not sure of. I have to see it on Monday when I come over my dad's friends shop. But my friend who is a mechanic said that the heat shield of the catalytic converter is that one that causing the noise.
