Just an fyi: Any shop offering these coatings should know which to use on what part of the exhaust, the manifold is always hotter then a pipe so the highest offering of heat rated coating should be used, it may be that they have not done enough of them to know which to use yet which is understandable so long as its done correctly. I have a shop that I go to and all I have to do is hand them the part and tell them what its for and they know the heat rating required.Thanks all! That was exactly what I needed. Local shop had two temp specs for powders and was not sure which one to use. Have a great day!
