    I’ve been hearing some rattling come from my catalytic converter heat shield and today I decided to hit it and these little pieces of burnt metal came out of it. I was wondering what this is and if it is going to be an issue.
    Thank you.

    Okay, so it’s not the converter itself?

    Scratches, dents, and a lot of miles
    Only way to find out is to take the heat shield off. Luckily my heat shield deleted itself after 150k so it's easier to inspect...
