Shaun,
The woven material should stand up to the heat no problem, its the headers
Id be worried about. For longevity on the street I would not use a header
wrap (any kind). The wrap will promote corrosion by creating a very high
temp environment at the header since the header cant scrub heat. any
condensation etc. will promote rust like mad! Yes, even in stainless steel.
Most header warranties are voided if a header wrap is used. For strip only
use it should eek out a tenth or so by cooling the engine compartment. My
Jury is still out on whether keeping the exhaust heat IN the header actually
produces more power (high temp = less dense gas = larger volumes of gas=
higher pressures = less horsepower?? conversly high temp =high velocity...).
If you can get some "scrap" braided tubeing Id be real interested in trying
it out on my Jensen... (it eats plug wires due to tiny engine compartment
and big engine combo. I use the silica braid from magnecore, but it tends
to crisp out after a while.) My opinion, which is mine, ahhhemmm...

Ummm, I don't think you read my post right. This stuff withstands
ROCKET-THRUST and is guaranteed up to 2600 (yes, that's two thousand six
hundred) degrees farenheit. You'd be closer to melting your engine block
before this stuff would give way. SFT's sister company 'weaves' the same
stuff and it becomes the grout between the Space Shuttles heat tiles.
I fully admit that it might be very expensive, but I do know that many
professional drag racers, NASCAR and Indy/CART racers have had this stuff
put
on lines/hoses in their motors. Like I said, I don't know if it's ever been
done to a set of headers, but I have seen a motor with all of it's
hoses/lines
done in a combination SF2600/carbon composite mixed braid and it looked
beautiful. Yes it was a show car, but the guy must've had the money to
spend.

I don't think you should use it on the headers. The headers themselves
will heat up and kill the coating. Standard ceramic coatings can go up
to about 1300deg. You can certainly use it to insulate other components
from the heat. I'm going to tie-wrap aluminum foil or something until I
can get some material from Summit.
I think the tubular headers have more surface area and therefore
transmitts more heat into the engine compartment. It's also not as thick
as wall on those iron log we got rid of.
