From my experience with those in the past, I would guess they wouldn't get tight enough (even using pliers to pull) and would eventually lead to the wrap falling off. But that's just me, have you had good luck using them on headers in the past danoman?

 

Yes I have. They're just like plastic zip/cable ties except they're stainless steel. You can get them pretty tight actually. Nothing wrong with the hose clamps, I was just razzing you.

 

Now I'm in it to learn haha. I may give those a shot with my turbo headers for clearance reasons. I just always had an issue with them where I would pull and pull but they would not lock for .125" but it's worth another go. Thanks for the hard time lol
