Well that fucking sucks.
Like Cheebz said, you're not the only one who's had it happen.. I looked but I wasn't able to find any pictures of my bumper from when it got cooked in England. My tune was so rich that I'd regularly spit prolonged flames on shifts and decels. I cooked the paint clean off my bumper just above the exhaust.
Ideally you could just fix that light housing, then get a carbon fiber exhaust guard. Here's a pic where you can kinda see the one that I bought to put on my car after burning it's bumper.
*edit* But you're still an idiot... lol
