What the heck is wrong with my car? And no, you are not my mechanic.

Alright so I have an automatic 2004 Subaru Legacy sedan. Just had some work done to it but a new problem just started to pop up. I should point out I first noticed this just before I had the work done, so it is not related. But if it helps I had some oil leaking onto one of the spark plugs causing hesitation.
I am asking in the hopes of softening the blow when I do have it looked at this week.
So when I am at a stop light or sign and I hit the accelerator hard there is a rumble/vibration right under my seats, maybe a little further back. It can be felt and heard. If I accelerate very slowly this does not happen. No problems turning wheel, no noises while turning so hoping it is not the differential. It only happens in the above situation. I do notice that when I am at highway speeds that there is an occasional rumble but much higher frequency.
Possibly related. There has been a rattling of what sounds like a heat shield when I am driving. I have looked under the car to find the culprit but don't see anything noticeably loose. The sound also seems to be coming from the center of the car, under the driver seat, center console. Think there is a cat converter under there.
So any suggestions? I have been looking online and the only possibility I came across was something to do with the drive shaft or drive shaft bearing if I remember correctly. Does that make sense?
I am really really really hoping it is not my transmission. Really. I don't notice any slipping when driving or other transmission red flags. For what it is worth.
