So i have recently decided to go ahead and commit to polyurethane Transmission mounts and i have noticed more vibration in the cabin of the car.
Vibration feels somewhat normal and it not extremely aggressive either.
I'm also running factory engine mounts, and they are in tact.
Just curious as to if anyone could possibly relate.

Yes. Stiffer mount = more NVH.

This is common knowledge.

In my experience, poly trans mounts is far more noisier than any stiffer motor mounts i have tried. I'm using poly engine mounts and a factory style rubber trans mount, it's a little noisier than full rubber mounts, but still tolerable enough for everyday driving.
