I always figured it was the collision aspect and not just from idle time, although that could also make sense as the tailpipes can get pretty hot. In a rear end collision though there's a good likelihood the gas tank will crush up into the OTA pipes. Wouldn't take much time to melt through if touching and the car was still running, and that would likely result in a big fire.



FWIW, regarding the dreaded rattle, I used dynomat on the inside of my shields and it helped but they still would buzz occasionally off the 3" exhaust due to lack of clearance there. I bent these little aluminum tabs up to tie them to the chassis and never heard another sound from them

Not that you're wrong but if a collision were enough to push the fuel tank that far forward I would be more concerned with tank rupture, fill tube or fuel line damage as being more of a fire risk.

yes the plastic tank is rocks and the metal of the road then damage the plastic tank.
I was doing the temp heat gun and the temps are around 110 f of the gas tank in the summer ..next to the pipe area .
those collision shields are not damaged ..in front of the tank ..
