My original OEM muffler needs to be replaced, sounds like the car is going to fall apart. Isolated rattle to the muffler (17403-66041) located under the right-rear passenger. With all the online parts houses removing the diagrams I can't seem to find the part #s for new gaskets I will need. Anyone have those handy? I searched and found a thread that Beno stated 90080-43033 but want to confirm.
