I want to know this answer as well. It doesn't say in the specs what temperature is allowed, neither transient nor continuous. From Wikipedia: The heat stability of raw PVC is very poor, so the addition of a heat stabilizer during the process is necessary in order to ensure the product's properties. Traditional product PVC has a maximum operating temperature around 60 °C (140 °F) when heat distortion begins to occur.[25] Melting temperatures range from 100 °C (212 °F) to 260 °C (500 °F) depending upon manufacture additives to the PVC. The linear expansion coefficient of rigid PVC is small and has good flame retardancy, the limiting oxygen index (LOI) being up to 45 or more. The LOI is the minimum concentration of oxygen, expressed as a percentage, that will support combustion of a polymer and noting that air has 20% content of oxygen.

Supply Giant 6I52 Flexible PVC Reducing Coupling with Stainless Steel Clamps, 2.4" x 1.6" Inner Diameter for 2" x 1-1/4 Nominal Pipe, Black

Q: What are the ID of the 2 x 1 1/4 rubber coupling?

1 and 1/4 x 2 are the size if inner diameters

Q: Is it possible to use for car exhaust

I wouldn't. Exhaust pipes get hot and this isn't heat resistant.

Q: 2” to 1 1/4” adapter Is bigger inside opening than stated. Can a 1 1/4” p trap seal correctly?

I used to connect 2” to 1 1/2”. Both pipe were schedule 40. A P trap is normally a lighter schedule. You may need and adapter from 1 1/4” P trap to 1 1/4” schedule 40.
