Header and exhaust wrap question

Yeah I just got the wrap by itself, but did order a pk of 4 of the Taylor Ty's, I have two 25ft and one 50ft titanium wrap just just thinking the Ty's for down pipe, and use the safety wire since I have it left over from my rear brake kit to use it on the headers and the mid pipes.
I have used wire sucessfully -----------------
And my 505 has burned up every wrap I`ve used , including lava wrap. Now trying some full fiberglass /alum coated stuff, stinks and smokes like its gonna burn at first , but queits down after a while .------------
