Thermal paste them to the inside of a pice of Al pipe square, hex for 3 searies. then run your hot pipe through the middle. Add some cement for filler .Add a layer of 1/8" foam between the filler and the teg. like the flexable sheet stuff they wrap new dvd player's in . This will vaporize out during the brakein period leaving a small air gap to alow for thermal expansion of the chip sets. Also the cement would act like a capacitor, slowing and evening out the temperature spikes.
Also changing from direct transfer to IR only

Side effect that hasn't been bought up yet .
It will keep charging when you turn off the car ,the exhaust is hot for a long time after shut down, this may make up for some of the shprt commings. .Active cooling may be necessary for cool down.

Would just after the catalytic converter be the best place as it is a constant temp when active.? With good temperatures at low engine load.?
Quote:
The average light off temperature at which the catalytic converter begins to function ranges from 400 to 600 degrees F. The normal operating temperature can range up to 1,200 to 1,600 degrees F. But as the amount of pollutants in the exhaust go up, so does the converter's operating temperature.
