Exhaust system use of a ceramic coating applied via thermal spraying. This not only reduces heat loss and lessens back pressure, but also provides an effective way to protect the exhaust system from wear and tear, thermal degradation and corrosion.

The entire system conveys burnt gases from the engine and includes one or more exhaust pipes.
