FYI. The stoc V6 exhaust manifolds are s/steel apart from the port flagne. The construction is an airgap clamshell design with external heat insulation under the heat shields. The stoc Y pipe also has heat insulation material under its heat shields and is all S/steel.The reason wrapping normal mild steel headers/pipes is a bad idea,because at elevated temps mild steel oxidises at a faster rate than s/steel. A combination of high temps and the amount of water in all exhausts causes rapid oxidisation from the inside of the pipes out....wrapping mild steel speeds thisup. In very bad cases a mild steel wrapped pipes will perforate from the inside out.On the manifolds and Y pipe I'm quite well up on the design and its materials because, apart from Ford, you know where I worked in GR.
