Ok I know the reason for this...I have an EDGE and I got this kit about a 16 months ago...the shop installed it..and about a week later it melted right thru my vent tube (In the same bundle as all the rear wiring). The shop had to install heat blankets under my truck as well as replace the part ($955.00). So I bet the shop *****ed at Magnaflow, and that was there solution. Since then the system works fine, just have that heat blanket under there. There must be something different with out trucks. It is only in one area that it touched....
