Has anyone here used header wrap? It'* a product that comes in a roll and you use it to wrap around your exhaust headers to trap the heat in the pipe so it cannot dissipate into your engine compartment. The reason I ask is because on my engine the crossover pipe goes directly over my transmission and under the throttle body. The gap between the throttle body and the crossover pipe is less than 2". The entire intake gets HOT because of this. I'm surprised the rubber and plastic components don't melt because they get so hot that you cannot even touch them after only a few miles of driving.
In most cases, do the headers have to be removed to do something like this? If so, I have no idea how to do that.
Has anyone here done this procedure? Thanks!
