Default Odd rattle/vibration

I have a 93 eg coupe, b16 dc-421 headers with test pipe
Between 1200-3000 rpm im getting a weird vibration/rattle noise sounds like its coming from the back of the motor. All heat shields are removed exhaust and headers have alot of clearance. If i keep the gas pedal pressed hard i can hear it but if i keep it down only slightly and go through the 1000-3000 rpm range there is no noise. Im at a lose here guys the noise has been bugging me for so long and i just cant figure it out.

I was thinking seeing is how im pretty sure ive checked 99% of what i thought it could be. By any chance could it be caused by my motor mounts i have hasport billet race mounts and the engine doesnt move really at all. Could this be the culprit?
