Is this noise RPM related? Does it go away, or get quieter/louder if the gas pedal is pressed?

the noise is heard when the vehicle is idleing and it can be very loud. it sounds like a belt squealing. the dealer has identified it as being associated with a gasket in the exhaust where the manifold connects to the rest of the piping. the gasket has been replaced multiple times but the noise returns within a few weeks or months. i was wondering if anyone had an alternate fix since replacing gaskets isnt working.
