I think it’s the under tray, i just can’t prove it. it’s really annoying and it makes my car sound like horrible. any idea on how to fix? it happens in the beginning of the clip i sent

Would it make sense to get a second person so that one of you can be under the car, and the other can start the car to try to duplicate the noise?

Can you prove it is/is not the under tray by removing it, then performing the same action?
