Why would someone want a ceramic header coating on their exhaust system? This procedure is gaining popularity among performance enthusiasts. Here are some reasons why.
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.
You will another benefit with ceramic headers. They look much better than plain headers. Anyone that wants a custom look will appreciate ceramic headers. Ceramic coating also keeps the headers from corroding. The coating will not come off, once properly applied.
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.
The ceramic coating is usually applied at extremely high temperatures. The temperatures may reach 20,000 degrees Fahrenheit. This is usually a professional application. There are some products out there to coat your headers yourself. Not much is currently known about them. There are several types of ceramic coatings. Tungsten and titanium are two of them. Because ceramic can stand extremes of temperatures, it is used in other engine parts. It is not uncommon to see ceramic coated intake manifolds. Pistons and valves and most other internal parts can be coated. This increases efficiency and reduces wear a great deal.
You may find a few a few obstacles with ceramic header coating. The engine may take longer to reach operating temperature. If you have any weak area in your exhaust system, it may expose them. The excess heat will be the reason. Of course, this may also give you the opportunity to fix weaknesses before they cause problems.
