However if we think the coating will interfere with the fit of the header to the motor or the header to the mating exhaust part we will typically mask off those surfaces.
Ceramic coating turbo downpipe.
A ceramic header coating also provides protection against the corrosive materials in the exhaust.
How important is it to have the downpipe coated.
Coating your headers in ceramic improves their heat resistance and keeps them from being tarnished or damaged by the heat.
If the manifold or pipe has been coated not only on the outside but the inside as well it can make it almost impossible to repair since it is very difficult to get the coating inside off to.
I just installed a prl downpipe and i m now reading a number of people saying to get a turbo blanket and the downpipe either heat wrapped or ceramic coated.
In other words ceramic coated headers look and function the same on mile one as they do on mile 300 000.
On naturally aspirated motors non turbo we will typically coat the inside of headers as deep as possible.
On turbo components the thermal cycle process can go from glowing red to cool as a cucumber.
Remember our coating is about 015 thick not a thin paint.
Over time this can weaken the cast housing.
Even if you bought titanium or good stainless steel parts a ceramic coating for headers exhaust pipes and turbo parts just to name a few actually improves their performance.
You should always have an expert advise you on which type of coating will be best for your parts and the way you plan to use them.
The ceramic coating is applied evenly on both the inside and outside of the exhaust pipes preventing hot spots that can cause metal fatigue improves the laminar flow of your exhaust gasses prevents rust and corrosion of the ceramic coated parts.
