Heatwrap is nice to use as-well commanderwiggins!

We have used ceramic coating on the manifolds for quite a few years and really like the results we've gotten this way as far as exhaust temperature is concerned. The coating decreases that transfer quite a bit, the wrap tends to "trap" the heat in the metal from our experience.
