Header Wrap
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.

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

I wrapped mine and it took forever. I did wrap each one to the collector. That could be why it took me so long. I ended up cutting it off before I installed it. I had it cera-metallic coated by Crucial racing. I'll see if I can dig up a pic.
