I just noticed that my00' is making a nasty RASPY sound @45K rpm. The raspy sound is only heard between 4000-4600rpm. No rasp before 4k or after 5K. My00' has never made this sound. No cel and car is performing as normal. I'm hoping that it is not a mechanical issue. The sound seems to be resonating from the engine.
Any help who be greatly appreciated.
A vid is attached showing the raspy sound and before raspy sound (note: the date on the vids were not updated).

Check the heat shields tightness around exhaust system?

A cracked lower header mounting bracket can make a raspy noise around that RPM. Look carefully sometimes its hard to see. Will just be a line through the metal.

Cat. converter / test pipe coming apart?

Thanks GUYS! I'm going to have it checked on Monday. Hopefully the problem is exactly what you stated.
