Catalytic converters and exhaust systems rely on the heat from the exhaust cylinders to operate properly. These exhaust coatings are engineered to not degrade or lose color under extreme heat.Įxhaust coatings also help keep your vehicle operating properly. There are different exhaust coatings for different needs, but most of these coatings can withstand somewhere between 1250☏ and 1800☏, depending on the formulation. These special high-heat ceramic coatings are designed to withstand high temperatures. Extreme heat contributes to parts damage, corrosion, and thermal oxidation. In fact, ceramic exhaust coatings can reduce the surrounding heat to the rest of the engine by about 65%.īecause the neighboring engine parts are protected from escaped heat from the exhaust manifold, the life of the parts is extended. Normal stock engines lose some of that heat in the engine through the exhaust headers, causing the surrounding engine components to heat up.Ĭeramic exhaust coatings insulate that heat throughout the exhaust system, making sure it escapes through the exhaust pipe. Ideally, this heat should be expelled from your engine to the outside air via the exhaust system. This is caused by the temperature of the exhaust gas in your vehicle which is typically 500☏, but can be as much as 1500° Farenheit. Your car engine normally operates between 190☏ and 220☏. Heat Tolerance, Thermal Efficiency, and Engine Protection
The ceramic coating provides protection and durability that uncoated pipes, headers, and manifolds do not possess. Over time, these gases can corrode the metal. The chemicals in exhaust fumes are corrosive and toxic. This prevents rust formation from thermal oxidation.Ĭorrosion protection. Ceramic exhaust coatings provide a durable, heat-resistant seal to metal surfaces in your exhaust system. Ceramic coatings protect the exhaust system from corrosion in two ways. Uncoated exhaust headers rust more easily than exhaust systems coated with a high-heat resistant ceramic coating. Exhaust Coatings Help Prevent Corrosion and RustĮxhaust coatings provide thermal oxidation protection, meaning your exhaust systems are less likely to develop rust or corrosion.
There are several reasons to get your exhaust systems or headers ceramic coated. Ceramic coatings are different from traditional powder coating, as ceramic coatings are meant to withstand high temperatures, as on exhaust systems, manifolds, or headers.
