I guess I got lucky? Three pipes on the Dez and not one's come loose (yet) - they're all HPC ceramic coated too.
I held the chambers between my legs so I could keep both hands free (wear pants and if you have a towel, use that too - itchy stuff) - started with a couple overlapping wraps about 2" or so from the end of the pipe - then overlapped the tape about 1/2 the width of the tape towards the flange.
Once I got up against the flange I made a single overlapping pass, then started working back towards the stinger. Keep pulling the tape as taunt as possible. All in all, it's probably three layers thick up near the flange.
Did you get the stainless steel "zip-ties" (they look like zip ties, but no notches) with your tape? - mine came with four per roll.
Throw a hose clamp, or safety wire - something steel that can deal with the heat around the tape as close to the ex flange as you can get it. I have the stuff strapped on both ends.
Oh - when going around bends and such - at the point of greatest curve, flip the tape over and make the side that was against the pipe the outside - fold, if you will. Do it on both sides of the bend. You'll see how it allows the tape to stay up tight against the pipe, yet allows you to change the direction of the wrap.
Check out this picture:

Since you have a ceramic coated pipe, you may want to get the tape wet before you install it - will allow it to stretch a bit more and give you a better/tighter fit.
It will smoke a bunch as it dries, but I've not seen any problems with corrosion yet on my pipes (they've been wet from puddles/washing and such).
The stuff smells funny for the first hour or so too. Kinda like new muffler packing but more intense.
