It is a dual piece drive shaft, more meant for fuel economy than spirited driving. When you bypass the speed limiter you're on your own. I am sure ford has done rigorous testing on these Driveshafts and set the speed limiters accordingly.
You take a car meant for 118 mph top speed, and bypass the system and take it 30mph over the safe zone you should expect problems.
While we all know the Mustang is a fun car, fords legal team has specific processes in place to protect the company, speed limiters are one of those protection, you bypass it, they're off the hook.
If you're hell bent on doing 150-160, replace the drive shaft with something meant to take the abuse.
Some of these guys who have blown up their drive shafts have been lucky, the RPM and speeds those drive shafts blow apart can send shrapnel into the body and floor. So it is modify at your own risk.
