Hi guys, I drive a 2001 boxster, and my car has started making this weird screeching type sound that comes on and stays on after about 5 minutes of driving. It sounds like it's coming from the back right of the car, or maybe underneath the car from the rear right catalyst. I'm not exactly sure what it is, but the car drives fine and there are no dash lights but the noise is completely unsettling. I thought it might have been the AOS screeching, so I replaced it with a new OEM part but it hasn't gone away. Any advice is appreciated.

Does anyone know what this noise could be?
