Broken Cat?

[idefix]

Hi guys,

got this strange noise when the car is cold, especially in the morning at around 2500 to 3200 rpm.
After 5-10km the noise is gone...might be the catalytic converter.

What do you think?

Some sort of heat shielding?

Also sounds like an exhaust bracket has become unwelded to the back box.

Heatshield might be an option as the noise goes away as soon as stuff gets warm in the back.
I hope it's not one of the cats as i have absolutely no idea where i should get one iolin:

I had a rattling from my exhaust plus car failed MOT on emissions

Was found to be a cracked rear cat pipe - common fault apparently but easily fixed with a little welding

Heat shields do rust away have heard as well, mine was fine just the cat pipe

Hope this helps
