Exhaust wrap is a lighter, and possibly edgier, alternative to heat shields. Anyone who has ever had a boot actually burst into flame while riding a bike with unshielded pipes knows how hot an exhaust can get. Proponents of exhaust wrap claim that motorcycle exhausts with heat shields actually do not get hot enough. Wraps keep heat in the pipes so it can only escape at the end of the exhaust. The theory is that the hotter the exhaust gasses, the more efficiently they will flow. Design Engineering, Incorporated, claims that the pipes their products wrap must get to 204 degrees Celsius before the silicone spray that coats these wraps begins to bake.
