Forced air heater so this exhaust line is out of sight?.. we have what appears to be a fiberglass type of cloth wrapped around a short bit of pipe between our engine exhaust manifold and the RW injection elbow.. looks (and may well be) like roving. It's simply spiraled around the pipe.
Alternatively, in industry we use preformed f/g insulation that is jacketed with either foil or a white cloth layer.. if the run is fairly straight you might find some of that at an industrial cladding and insulation supplier. Regular foam pipe insulation would , of course, melt....
