What fell off of my car?

2005 Nissan Sentra 1.8 SE
When parking my car, this fell off as I pulled forward and undercarriage was scraped slightly by curb. What is this? Can I drive without it until my appointment?

Looks like a heat shield, maybe around the exhaust manifold. Probably OK to get it fixed when convenient.

That’s a heat shield.

It fell off. That’s how important it was!


Don’t park over dry leaves, grass, or anything else flammable…

Take it with you to a muffler shop and have them reattach it.
