got it loud and clear

once i got it all wrapped up on my aaen pipe nice and tight (after having soaked up the wrap with water) and fixed it with stainless-steel-wire, and run the motor to dry out the wrap.
only concern left, will the wrap not move down from the broader parts of the pipe towards the ends after I have some heat cycles and hours running the zilla ?!? hope not cuz that will be a waste of bucks i guess then ...
