It could be a self selection bias here where the only people that get one piece driveshafts are the ones that want stiffer response everywhere in the drivetrain by add stiffening, more NVH is added as input and the chassis + one piece driveshaft gives the resonant vibration transfer function. I also have a DSS aluminum without any bushing/mounts and its fine even to 105mph. Just a datapoint.

This is also assuming the tail bushing on your trans isn't wiped
Are you MT or AT?
