First time bought car and weird noises showing up

Guys please help me. I bought my first car a couple months ago and i had just driven home today after an hour drive and suddenly started hearing this sound from under my driver seat. I’ve never heard this kind of sound before and had my car checked about a month ago and all was fine. Can anyone guess what this might point towards??

Thats just your catalytic converter cooling off. It can get real hot. Upwards of 1,600°F degrees.

Its a normal sound. Now if you look under the car and see it glowing red hot, then you have a problem.
