Wrapping Headers

I agree with famous Bob. I have replaced the headers on my wives car with headers that are ceramic coated inside and out. It actually runs cooler in the engine compartment than when it was wrapped. These scavenge heat so well that it takes longer to get up to temperature.

Just a thought.... all the heat that was dissipated by unwrapped headers is now going to go directly through the turbo when they are wrapped. It seems logical that wrapping your headers would increase turbo temperature.
