K guys, need some help with my 3VZ;
was going to install my "bigbird" lip, and I noticed a bulge under my front left bumper
another view
now, i was wondering, a) is this normal, and b)if not, what equipment runs on that side, and how big of a risk of damaging that stuff if I bend this back.
also, what sensor is this?

its the thing attached to my exhaust headers, I believe it's the o2 sensor, but not sure. car was throwing a CEL, and when I was taking off my heat shield, I noticed that the wire had lost insulation at the tip, and corroded like hell.
