how does this header wrap hold up
a lot of the riding i do is in deep sloppy mud.
i can imagine the wrap wont last more then a few rides

I wrap the head pipe with the stuff then about every 2 inches tie stainless steel safty wire around the pipe.
BigDesto after the header wrap my bike runs cooler
even in the tight 1st. gear single track trails
I do run sunoco purple gas (110 oct.)and that helps it stay cool.

I'm lookin' to replace my stock h-pipe (big ding in it, bought it that way) which header pipe would you go with?
Can these be popped/blown out? Some have guessed that a body shop could weld a stick onto it and slide hammer the ding out. Anyone experience a good fix? Thanks, TC

that it would create some temp increase,because it is not letting the heat dispurse!?????

I agree with BigDesto, the heat has to go somewhere, I think most of it goes out the back but the increased power claims would have to come from the combustion chamber I would think.
One advantage I can think of with wrap compared to a heat shield is riding in tall grass or brush. At one of our races last year a guy on a brand new 426 got off the trail and ended up down in a gully full of tumble weeds. He was clutching and pushing trying to get out and ignited the brush. He said he tried for a few minutes to stomp it out but when he saw the melted fuel line dripping fire he came to his senses and started worrying about himself. The brush was so dense he had to crawl over it and I guess he was lucky to outrun it. I have pictures but no url to post them to. If you would like to see them leave your email address. Or, I could send them to somone who knows how to get them on the page. Made me a believer in insurance.

It is similar to shortening the pipe. Eg. tuned for higher rpms.

I was told that if you keep the heat in the pipe it will increase the exaust speed and scavenge the hot exaust out of the cylinder better. That in turn will help cool the cylinder and head.
One thing for sure I used to add coolant every time I rode tight trails and now I dont.
for motocross every thing may be differnt, I dont know.
