Other companies apply cosmetic header coatings that have minimal effects on heat insulation and instead are purely for cosmetics. These header coatings are shiny or colored and really will not improve performance, but they do look nice. Swain Tech Coatings is the only company to offer a true insulating thermal barrier for exhaust parts. This external thermal barrier is applied approximately .012″ thick, has a white matte finish and does a tremendous job of keeping the heat inside of the pipes to improve scavenging and reduce under hood temperatures.
About halfway down the page right after the pic of a coated exhaust manifold and muffler.
