Ceramic coating looks like this. (or you can get black) Cost $288 delivered (Sept 2014). I got mine done at HPC in Leongatha. Sent them in a post pack for $13-.
My previous set are good as new after 6 years, no sign of any rust. They do the inside as well. They do dull slightly over time. I think they look better than stainless and you get the heat reduction properties as well as longevity. Just my opinion though.
I put mine in today at CIC Ceramics in Perth I hope mine come back looking as good
The guys at CIC were saying not only do you get corrosion protect but also, to quote from their website;
'The coating is a thermal barrier, by keeping heat within the manifold, you’re going to accelerate the exhaust gas velocity which reduces back pressure and reduces fuel contamination due to reversion. This is a performance benefit. Second, you’ll reduce the surface temperature of the manifold. This means if a person comes in contact with it, they are less likely to be burned and leave skin behind. If there is a component close to it, it will not see as much heat as it would with an uncoated manifold. In addition, not as much heat will be radiated under the hood or into the engine compartment. This reduces the underhood temperature which, again, reduces the temperature of surrounding parts, such as, alternators and starters. It also reduces the amount of heat that can be drawn in through the carburetor, which is a secondary performance benefit.'
Well worth the cost for the looks and added performance IMO!
