Well we can say it isn't normal.
I'm fairly certain I've got some wicked EGT's going on, enough to do the following to my rear bumper.
Has anybody shared this unlikely quinkadink? Exhaust is free flowing, 3" DP/throughout no cat, no res, Vibrant muffler. Didn't really have this problem for the last year and a half until tonight with a small 200 mile trip.
Check condition of cat. Any flavor you want, wait for it to glow, pressure check it, sun check it, whatever you do. Personally I like to look through them to tell. If it looks like your looking into a dim room or there is a tint, it's shot, probably making allot of heat.
Don't think it's anything turbo related. Turbo's can glow red hot in track conditions to where you think the sucker would melt but it does not.
Perhaps a creature built a nest that became kindle. I really don't think the exhaust is too close, my dtm brospeed is pretty close on the bottom, then points up following the bumper even more, into the air (dtm....) It gets pretty toasty. The materials shouldn't fail in normal operation. The closest suspect is again, cat.
You've probably guessed this I assume?

Does it exit before the upturn of the bumper?
Mine would get toasty on long drives when the tip didn't go past the parting line, it would then sag the bumper and touch. Add to that a single wall tip like yours, and you get melting.
