header/manifold wrap questions

ok I cant afford to get my headers ceramic coated so i opted to buy some heat wrap from a buddy of mine....only thing is i dont know how to join the wrap on the pipes!? Somebody told me to use coathanger wire...that seems pretty backyardish...does anybody know the best way to wrap headers /manifolds, and how to make it tight and stay tight on the pipes?

Bailing wire or hose clamp.

Some eone sells a clip for it but I can't remember who. I know they do because it came with a package that a buddy bought a few years ago.

I've had very good luck with regular solid copper telephone wire, it's dead soft so you can twist tie it tight and trim it close, it does stay tight

insulation burns off in a heart beat, then it is just about invisible on the wrap

I do use hose clamps on the collectors, to much air at speed, the wrap will un-ravel

Header wrap manufacturers make straps just for that purpose. As an alternative we have used stainless steel safety wire for years. We twist it tight with the safety wire pliers.

The stainless band wraps are the best, and look the cleanest, but I too normally use safety wire.

I used header wrap despite the manufacturer stating not to.
Luckily I took it off in time, it tends to attract moisture and rust the headers.
I just had a few holes to get welded up.
I do live in a humid part of the world and the car was not used daily to heat off the moisture.

malc,
fair to very good chance moisture had very little to do with the pin holes...

you burned the pipes from inside,
due to the exhaust temp "exceeding the pipes mfgr allowed max temp".....
that's why they said don't wrap them...
incase you do have wicked hot exhaust temp's

yes, the wrap traps (more) heat in the headers, yes the pipes are hotter wrapped....that's what you want for more exhaust scavaging to gain HP/tq

nah, you can't match central Florida for wet!
wrapped my $99 headers to keep heat out of car,
they were fine after 8yrs (?) of relatively normal exhaust temp
