Probably. That is usually the first things to loosen up.

That is until you have a muffler rot out from the inside, but that is a completely different noise. :rotfl::rotfl:

i think that might be it, u know where it would be located

Yeah. Sadly the stock exhaust is covered in them. Follow your ear.
