Header wraps are designed to keep the heat in the header to improve scavenging of the cylinders. Keeping the heat in the header allows the exhaust speed to remain high. (the right idea) Header wraps, by keeping the heat in the header, also reduces the radiant heat in the engine bay

The one with the crack has 10 hours i just replaced it. I think the coupler was put on to tight. There needs to be 1/8 inch gap. It seems to be doing ok with the crack
A crack that big after 10 hrs will probably be shredded in another 10 hrs.
