i dont mind how it sounds, and i dont care about what you like, but it is sure, that in 25psi, damage will occure. amount of damage depends on many things, but it will happen. your turbo is gonna probably last for some time, but i would not take that risk.
on a T4 the damage is greater, and will break up sooner.
if you know what makes that schatter sound, you know what it does to your turbo.
