The databases are on Exadata two node RAC. Each RAC node has 14 CPUs. These are non-production databases, so there is not much activity. I checked in OEM and CPU is not a limiting factor during export. Even in your test case, the time increase is less than 25%. In my case, it is close to 100%. Is this kind of time increase expected with plenty of resources available?

You could have 1000 cpu's... if you are running your Datapump in a single session, then you only get to use 1.
