Ceramic coating exhaust systems leads to a very low heat transfer coefficient because of the thermal barrier content within our polymer ceramic coatings. This means that the exhaust system itself will not absorb as much heat allowing that heat to remain within the system. This is why manifolds or headers are commonly seen with a ceramic coating, to keep under bonnet temperatures to a minimum.
For motorbike customers, the same principals apply. By maintaining heat within the exhaust rather than the system absorbing it you get a much more comfortable ride, as well as increased power.
As a result of retaining heat within the exhaust system, exhaust gas temperature will be maintained at a higher level, increasing velocity. This is where the increase in power comes from.
