I am thinking of stealing some of the heat from that pipe to heat WVO in my trunk. I am thinking of I wrapping my exhaust pipe just in front of the muffler with some copper tubing and then run it up into my trunk. Then build a loop that surrounds my WVO tank. Fill the loop with fluid, likely pure antifreeze, and allow the heat differential in the fluid to move it around.

My question is, how hot does that pipe normally get? I certainly don't want to boil my WVO in my tank. Especially since I'm just using the plastic cubies that the oil comes in new.
