I have a JDM ITR header on my car with no heat shield.I'm wanting to do something to get some of the heat out of the engine compartment.I was looking into using header wrap made by Thermotec until I came across this"all header wraps contribute to shorter header life due to the intense heat within the wrap"I saw this in my Pegasus catalog.Has anyone had any bad experiences on their car using this stuff?If so I would like to know what, or does anyone know of another way to go about this.

 

The life of your header will be shorter but I wouldn't worry about it. They are talking about years and years......Otherwise, go with heat sheild.

 

not to second guess but where did you find this information?

 

Go ahead and wrap it you shouldnt have any problems.

 

My friend's wrapped header cracked awhile ago. I don't know if it was the cause of the wrap but I have hearded that it will cause it to crack.

 

Just say no to rap.

 

I'm getting my JDM ITR header jet-hot coated.. next time we meet @ an autox you can look at it.. I'd say jet hot coating it is worth it, specially in my case since it's not on the car

 

I got my info from a couple of racers that use the rap!

 

I have heard something about water and wrap= bad.....

something about water being soaked into the wrap and cracking the header....
i dunno much, i heard something like that....

 

Ceramic coating is better for a number of reasons.

1. lower under hood temps
2. extended header life (less rust)
3. better flow due to the ID of the tubing being smoother

Wrap will retain water (when car is not running) which accelerates the rust process, plus it allows more heat in the tube material instead of the exhaust.

Fast94GSR, I hope you didn't wrap that header.

 

Thanks Dave and SMSP,Just sucks because the header is on the car.I guess I'll get off me lazy **** and take it off and send it away to be coated.
