Exhaust sound

friends merhaaaba. My exhaust sound suddenly changed. Groans. Behold, if you throw wood on the stove, it growls. What can be the problem? I lift the tip of the exhaust up with my hand and when it gets up, it sounds like there is a connection problem somewhere, but I couldn't see it. Normally, when you hold the exhaust and lift it up, does it get steady? What could that sound be?

we cannot say anything without looking.
