Is header heat wrap a good idea
i know that you gouys out there with turbos use the stuff, but is still a good idea on N/A cars.
I want to use it to reduce cabin and under hood temp and picking up a few hp (if any at all wouldn't be bad either)
is this stuff any good from both a performance and comfort stand point?

I don't reccomend it. I wrapped my 12A RB headers and they ended up melting down and then cracking. This was after cruising and spirited driving at 90+ MPH for a while, but I still wouldn't do it again even for less aggressive driving. Try the coating or leave them alone.

It's a smart investment. Wrap them and you'll be spending another $150+ for new headers. Take the advice and don't wrap them.

What about coating and then wrapping? Does that solve the issue of the wrap killing the header, or would the header still fail quickly? I am thinking of doing this for heat and noise reasons on a turbo car. I probably won't wrap the turbo header (don't want cracks), but it would be nice to do the downpipe.

Ceramic coating completely covers your manifold and turbine. I have measured up to 100 degree drop in an engine compartment. Safe to 2000 degrees.

There have been tons of headers that have developed the problem over time. I think two months is kind of a short period of the rust to eat through the header, but it will happen in time. I used header wrap on my endurance rx7 and it did the trick keeping heat down, but I could never cover the whole thing. Thermal coating keeps the temps down just as much if not more then header wrap, and it covers the entire header, and great for turbines because there is no bulky heat sheild or heat bonnet.

my headders are made of thick walled steel tubing...the kind used for high pressure fuel delivery. so im thinking that the headers can stand the heat of being wrapped...but im thinking all that extra heat will go into my exaust and mess up my back pipe and WRX muffler...am i nuts or should this be a concern?
