Ceramic header coating is a popular procedure for performance enthusiasts these days. Why are so many people choosing this method?

Ceramic is not a good conductor of heat. This makes it a very good insulator. If the headers are insulating well, more heat will stay within them. This means there will be less heat to warm the intake air. Hot exhaust gases will make their way out of the headers and into the pipes. The intake air will be cooler as a result. Cooler intake air will give you better performance. The air will have higher oxygen content to it. This is the reasoning behind many intake air modifications. However, that is where many intake modifications fall short. They do not account for exhaust gases heating the engine compartment. This will decrease their efficiency. Well insulated headers translate to a cooler engine area. Ceramic headers can also make intake modifications more effective.

Ceramic header coating will increase the temperature of the exhaust gases. This will cause the exhaust to escape faster. It can be the difference between breathing and deep breathing. This will increase the efficiency of the engine. In some cases, the internal parts of the header will also be coated. This is said to increase efficiency considerably. Less heat also translates into less internal engine wear. This can save a great deal of money over time.

There are more advantages to ceramic coated headers. They will look better. You can have a special appearance. The headers will also resist any corrosion. The ceramic will be a permanent part of the exhaust. It will not come off.

You will not usually see an entire exhaust system coated in ceramic. It would be a very expensive modification. It may also not be very effective. The main reason to coat headers in ceramic is to keep the engine area cooler.

Ceramic coating is usually done by professionals, with special equipment. It is applied at very temperatures. 11,000 Celsius is not uncommon for this application. There are ceramic coatings for self application. Not much is known on them at present. Ceramic coatings come in several types. Among them are titanium and tungsten ceramic. Ceramic is also used to coat many other engine parts. Its ability to withstand high heat makes them perfect for coating pistons and valves. You will also see ceramic coated intake manifolds as well as other parts. This makes the parts less prone to friction and wear.

There may be a few disadvantages to ceramic headers coating. Your engine may take a little longer to warm up. Any weak points in the exhaust system will show up. This would be from the added heat.
