Happy Thanksgiving everyone!

Can anybody help give me suggestions as to what my problem might be?
Just started happening tonight...If I pick up speeds above 65mph on the freeway, I start hearing a thumping noise (slightly higher pitched, but not quite high like a ticking sound) that sounds to either be coming from the engine bay or slightly below me. The frequency of the noise increases as the speed increases, but not with RPM. This only happens at 65+ mph and doesn't matter if there are bumps in the road or not. At first, I thought I had caught something in my grills or the bottom of the car and was dragging something or my tires were screwed up but those don't seem to be the problem.

I don't feel any vibrations in the steering wheel and I don't think I feel it through any of the pedals. I'm 6MT btw. Could it be bad engine mounts or something?
