The ceramic coating has the advantage over the wrap from a durability point of view. It will not be damaged by engine fluids unlike the wrap which will degrade if it comes into contact with engine oils, degreasers and other fluids under the bonnet. For maximum heat retention, both the wrap and the liner must be made. While one might think that ceramic coated manifolds offer the best corrosion protection, Jeff explained, “Ceramic coated mild steel and even stainless steel manifolds can also be affected by corrosion.

The ceramic coating will help keep external surface temperatures lower than a painted or chrome-plated head. When asked about ceramic-coated headers specifically, as well as his opinion on application methods, he said: “The connection points from the primary pipe to the header is the area that is usually the first to show signs of corrosion if the application is of a higher quality. When it comes to exhausts, Holley’s Hooker brand has been one of the leaders for decades, and is a name that is synonymous with performance. We spoke to Jeff Teel, Hooker’s sales and customer service expert, and first asked him to explain the different coatings that can be found on manifolds, and which ones could be a problem for manifold wraps.

However, this will occur to a lesser degree depending on the quality or method of application of the coating, or the specific type of stainless steel used to construct the headers. The insulating properties of the header cladding will further aid the evacuation process, because unlike ceramics, the material used in the header cladding does not retain heat on the surface. You have a few DEI options, including coated fibreglass (centre) or powdered lava rock (right) in the Titanium series.
