God what a lot of misinformation on one thread!!
What IS obvious here is that the misfire on the right bank of cylinders introduced an amount of unburnt fuel into the exhaust which was then ignited by the cat. The scorchmarks look an easy fix for any semi-competent bodyshop.
Now, to scotch the rumours:
Firstly, a catalyst operates at circa 750C, hence a moderately warm day in Vegas is neither here nor there to a cat. These cars (and in fact almost ALL cars in production today) have spent more time in Death Valley, CA and in the Arctic circle during their development than you've had hot dinners.
Secondly, to "overfilling". This has absolutely no bearing upon what gets pumped into the exhaust. Any fuel vapour is either returned to the tank or is vented to atmosphere. None of it goes anywhere near the exhaust. The only issues about fuelling from empty to full is the fuel expansion when the pressures are different day to day, and this may have potential to escape as fuel or condensed vapour (but I reiterate - not into the exhaust). This has a very *small* potential for danger, but is negligible in the extreme.
