Does any one have any experience with header wrap.

1) It may increase performance by accelerating exhaust gasses by preventing cooling turbulance.

2) It may increase the header temperature beyond its capabilities, destroying the header.

3) It may eliminate the manufacturers warenty.

Just curious.

 

Wrap is a good idea, but it has to be applied PERFECTLY. If it isn't totally, absolutely sealed, moisture can get between the wrap and the header and you'll have rust and eventual component failure. A better idea would be to get the headers Jet-Hot coated, which is a ceramic/aluminum spray which is baked on. Expensive, but foolproof.

 

Any idea how to get that done? Any vendors you know who have already done good jobs on proven rides?

Thanks!

 

just to let you know, if its not wraped properly it may cause fire in the engine bay, and maybe to the whole car... I had headers on my wrx before, and it was not wraped and it was just fine.

 

Google search for Jet-hot coating (it is a brand name); I think there are a few shops which will apply this, but you'd have to mail them the headers. It isn't outrageously expensive, but it isn't free either, if you know what I mean.

 

Worth the Money?

 

Header wrap is fabric and is not waterproof or watertight , no matter how well or tight you wrap your headers willl not prevent the wrap from absorbing moisture.

 

Header wrap fires are caused by oil dripping on the headers, soaking into the fabric, then igniting. Not by poorly wraped headers spontaneously combuting. Just ask Miguel or James!

 

I'm not certain about this, but I thought that header wrap typically came with a paint-like sealant that you apply after the pipe is wrapped. In any case, it seems we both agree that coating is better than wrapping.

they sell this but its really not that effective, I used it on a wrap before and it mostly stunk for a while then burnt off! well it says right on the can its good to 1500 degrees which is probably fine on an NA car but on a turbo car that wont last long at all

that all said, I still use header wrap on my headers, it may have its trade-offs but header wrap os still MUCH more thermally efficient than the spray on coatings. I can turn my car off and put my hand on my header wrap, try that on a set of coated headers, on second thought, dont

 

Did you notice any sort of performance gain?

Anything positive or negative?

 

What kind of header wrap do you suggest? What kind of Spray is the best to use and lasts the longest? How long does it last?
