Exhaust Flange Gasket

[Rocket Man]

Do you know if there is a gasket that connects from Y pipe to the muffler pipe? I’m dealing with a 2003 avalanche z71 with 5.3. These gaskets seem to match up with the manifold side

On my 02 Denali there isn’t.

No there is no gasket that goes there, just straight bolt on
