Looks like I’m inappropriately dressed for this occasion, but this Hog’s exhaust pipe would never be caught dead in the same situation. Wrapped around the VERY hot exhaust pipe is a woven wrap, preventing heat transfer and subsequent nasty burns. It also helps to keep heat inside the system, allowing for improved exhaust fluidics which in turn increase horsepower. Oddly enough this “Titatnium” exhaust wrap is made of lava rocks! I can’t find a definitive answer about the means of processing the rocks into a viable thread, but I have a theory. Melt processing, it is sillica after all.

This would be suitable for extrusion and could go directly into use in weaving looms, without sliver processing. (so convenient!)

If anyone knows the real answer, please enlighten us all.
