WHY COAT YOUR EXHAUST?

There are many reasons for coating your exhaust, the main one being heat management. Ceramic coating provides a thermal barrier protection the exhaust from the damaging effects of extreme heat, prolonging the working life of the exhaust system.

The thermal barrier will also isolate the heat, keeping it within the manifold. This will increase the exhaust gas velocity and reduce back pressure and fuel contamination. The result of this is MORE HORSEPOWER! It is not uncommon to see as much as 5% increase in power, particularly on turbocharged engines.

The overall reduction in the surface temperature has many additional benefits, not the least of which is safety. Cooler exhaust means smaller chance of getting burnt upon contact. This benefit extends to all the underhood components that can be heat-sensitive like alternators and starters.

There are a variety of coatings on offer for exhaust maniforlds or headers. The most popular is our Cermakrome. It gives a newr-chrome finish, excellent corrosion protection and provides a great thermal barrior

For stock exhausts, our Colour-Guard Caast Iron is very popular, especially with restorers because it imparts an original, dark cast-iron appearance rather than the lighter appearance that is more typical of a bead-blasted finsih.

On cast iron, due to its high porosity, we recommend a base coat of Cermakrome before light sand blasting followed by a colour coating of your choice. On tube steel headeers we recommend Cermakrome or Colour-Guard over a base coat. In most cases single coating will be adequate.

For high performance applicatons we recommend MCS - our own insulating base coat which can be applied to the outside of the exhaust manifold or header, cured, lightly sand blasted, then covered with a layerCermakrome, cured and polished. This process will produce a high temperature handling capability allowing the exhaust to be used on 9 to 1 engines, which typically have an extremely hot exhaust gas.
