The heating effect caused by this must be self propogating, since the heated input air will increase the output heat, thus heating even more... is it significant? I have heard of people insulating their pipes so I assume it must make some sort of difference.
How much heat you get transferred is quite complex, depending on among other things the airflow through your engine bay and past those pipes.
I'd lag the exhaust to keep the heat away from everything else. Lagging the exhaust manifold and the transfer pipe you have will also improve turbo efficiency a little.
