Burning Smell Under WOT

hey guys, i'm trying to figure out what could be causing a strong 'plastic' burning smell under hard acceleration. i smell it when I do WOT pull from 0-100.
i have longtube headers w. no cats. friend suggested it might be a wrong paint used on the headers thats burning. i have c63 mufflers and have touched immediately after a hard pull to 100 and they were cool to the touch.

any ideas?

How long ago did you have the headers done? The paint they spray on it can take a couple of weeks to bake in and you'll smell burning paint smell during this time.

Jack it up and get underneath with a flashlight...

I have a feeling it is the sheathing of one of the many wires making contact. You do NOT want that happening IMHO
