Am thinking of doing that 3-inch downpipe story, but if I do then
I guess I'd coat that as well then. So in all coat the following:
manifold, turbine housing, downpipe and connecting flange. That'd

How about using a heat dispersing coating on the outside then?

Do the downpipe then? That can be done DIY.
