I will build a heat shield between the intake and exhaust also. Plus I will have cooling coming in from above the spinner and exhausting around the exhaust pipes themselves. So Im still mixed on wrapping or not, since I now have recomendations both ways. I know I will wrap where the exhaust runs over the redrive to insure it doesnt absorb too much heat. I may leave ther others alone since they are jet coated inside and out.
