Noise from F30 Exhaust startup
Gu guys, my car does this sound at the startup, coming from the exhaust. Not sure if I am being too much paranoid or there may be a problem.

You mean that "sandy" noise?

Yes, hear it.... not sure what it could be. Sounds literally like sand jumping in your muffler... or a thin sheet-metal which is oscillated. What engine is that? What cat converter? OPF/DPF?

Could be just a slight rub on a heat-shield too. An inspection will tell. But to me it sounds like an internal source.
