FI exhaust, burnt bottom bumper with Nismo?

It's crazy because I never really hear anyone say anything about having their bumper covered in black soot from having test pipes. Im sure I'm not the only one..

I have that exact thing happen...only difference is I stay on top of it and make sure it doesn't build up to that level and it comes off quite easily.

Also I noticed my back bumper is slightly covered with black soot.
Should I be a bit worried?

edit:
Test pipes vs HFCs and related questions
does TEST PIPES leave STAINS?
I searched google w/
site:the370z.com test pipe bumper

I find it a lot easier to find things on this site when I use google to search it.

All acceptable answers.

Yeahhhhhh... I have a Monterrey Blue 370Z and the back is hazy, I can keep the car clean for... 30 minutes, maybe an hour if it was raining when I washed the car, then drove around in the rain.
But a car wash takes all that crap off immediately
