Most people use the DEI Titanium header wrap since it doesn't require soaking in water to make it easier to apply. Some people use hose clamps and others have used the stainless steel ties they offer. I used a 50'x2" roll of the Titanium wrap along with the ties. I had barely enough for the header. I had thought about getting another 15' roll and redoing the header, but I figured it's good the way it is.
