The core temp if always going to be less than the engine temp. As such the temp downstream of the core is always going to be less than the core.

But a word of caution, they stopped using ABS and switched to PVC in exhaust venting for high efficiency home furnaces due to ABS off gassing when it got hot.

But I'm sure we are taking higher Temps there then what is sent in an automotive heater situation
