I was wondering if there was a cheaper alternative to the wrap ppl use to prevent being burned from the exhaust manifold/muffler's heat?
Header wrap...

Oven rope.

There are kits available at home depot and other places too, but the kits at Ace seem to be cheaper.
It's what I'll be using when I wrap my header.

Hmm.... never knew of such an animal...
think Ill try it! Im guessing I apply the goop(fiberglass) then lay the rope on to adhere to it/the header?Hmm.... never knew of such an animal...
I don't know, I haven't done it yet. I suppose you only have to use the "glue" at the start, and end... maybe a few spots in between? Maybe the whole thing? Not sure yet. I got the tip from here. Looked into it a bit, and it seems like lots of motorcycle guys use it to pack baffles. They say it lasts way longer than the factory fiberglass stuff that's in the baffles.
I'm definitely going to give it a go, and see how it works out.
If I don't like it, I'll just get header wrap. Would rather not though, since it costs so much more, ha!

I remember that thread....
I found some(header wrap) at the auto shop a while ago that was sitting underneath the shelf, the parts guy didnt know it was there, I got like 50' for a couple of $$. I got some clamps and sometime this year I have to do a wrap on a section of pipe, of my bike.
I would say if its wrapped tightly, and secured at one to start then the same at the end of the wrap. it shouldnt move. Basically you tighten down over the last wrap, then cut off the excess. that way you arent trying to hold a little piecs with your fingertips trying to push it under the clamp and have it tight all at the same time.
That is the wrap... then there are heat shields, that only depends on what your looking for or your imagination. Lots of ideas out there. Many different materials used aswell.
Talking about using this on a kart??

That's replacement gasket material for firebox doors; it's designed to handle heat. I personally don't know what it's insulation properties are, so be extremely careful, and use at your own risk.
Not saying it won't work; anything that keeps you from sticking to a hot piece of metal probably is a good idea. It's just that isn't what it was designed to be used for, and with no other documentation.....
There are several high temp refractory grade insulation materials that might work pretty good, but they totally fail the reasonable cost DYI aspect....

Is there any possibility that a good, cheap solution may lay in strips cut from fibreglass cloth that you would buy for bodywork/fibreglass repairs? I've been wondering about this...

You can't beat the real thing in my opinion,(Header Wrap),Here is a some on one of my wankel engines exhaust and fuel tank.A wankel engines exhaust temps can exceed 1600 degrees.

I don't know; but when you consider that "Glass Pack" mufflers use fiberglass, it would seem possible.
The materials I was referring to are all industrial grade; I've got half of a decent size box of refractory grade high heat silica glass wool that's usually used for insulation for heat treatment furnaces; at a former job, we needed to nickle weld 15 cast iron gibs for one of our competitors (LONG, LONG STORY).
Short and sweet; said competitor had F&*@#^^ UP; the OEM that he had been trying to impress was P!$$&D. They called around and found that we could could tig weld, and weren't afraid of trying to weld to customer spec.
They told us what we would need, and then came in and spent half a day showing the boss and I what we needed to do; time and material- they trained us to do what they wanted, and paid for everything. The down side? I've never done that type of welding since, and if I had to do it tomorrow to save my life, just take me out to the parking lot and be merciful...
When that job got sold to the next, I latched on to the ~ half box that was about to hit the trash. It was like $200 + back in the late '90's; think the rough equivalent to a roll of Owen Corning's best. Is that cost efficient for the double handful needed to wrap a small engines exhaust?

If it is the good stuff, and it sounds like it is, I'm guessing a thickness both sides will allow you to grasp the exhaust while under strong load and will have been running for a good long while, with only a warm sweaty itchy palm.
I was looking for some of that stuff for a lead smelting furnace(cast boolets), expensive stuff, ended up having to settle for refractory bricks instead. I'm sad I missed getting that stuff when I had the chance.

I broke down n got the real stuff. I talked to a friend of mine this morning and he too was looking to wrap his cycles headers aswell... Knowing I wasnt gonna be using a whole roll... we went halves on it... so I bought another can of silver to dressup the motor...
I wont go into the cost of the 2 items... GGGgggrrrrrrrr

Yeah, it's the good stuff; the bats are one inch thick. I could put a trim steel that I had preheated to 900*F, then built up with the Tig welder, then place it between two layers to let it cool extremely slowly. Depending on the size of the block, it would take between two and four hours for them to get down to room/ handling temp.
Got this at tractor supply just a bit ago for $10. I'll let you all know how it goes.
I'm curious as to how well this will work; at least it's not a bank breaking experiment...
It doesn't help that it's a niche item. Weather or not it cost very much to manufacture doesn't matter to the marketing dept; they know that if you want/ need the goods, you'll have to pay their price....

Well, someone please tell me how the rope trick works please..... If nothing else but the "cool" factor, this would look neat and make people ask about it...... and/or the kart....

As a practicingmagician for 32 years now, I know a few rope tricks, 
My wife is my "test dummy" for new /old favorite rope tricks, especially the rope handcufff trick. Has many uses ,gentlemen...... As far as the kart thing goes..... I was thinking it would look neat if you can knot it like how i make paracord bracelets.... or even just a simple braid around it. Now that I think about it, I might try to wrap one of my karts with a fiberglass sheet, then wrap/braid over that with a 1/4" cotton kern/mantle rope..... the glass will block the majority of the heat, and protect the rope from just burning up..... ???

...nice theory... ofcourse if someone were to give you some wrap... u could use ACTUAL 50/50 cord... braid it to width... and vwalla... dont have to worry bout that melted plastic smell AND 'have' the actual mats that the 'military' braiding is used.
But if u insist in doing the fiberglass idea... id check the thickness of the baffles they put in glasspaks as a possible reference for how thick of a fiberglass layer youll need...
