Yea, marko's right. And it looks like they plugged the hole with something otherwise you would hear (and smell) your exhaust.
It's emission related. When the engine is cold the secondary airpump pumps fresh air in the exhaust to warm up the cat and compensate for the richer mixture.
Probably the shut off vavle or the secondary air pump broke and bypass it that way.
You might get the check engin light on.
Also you probably hear a laud noise at cold startup that starts about 30 secs after the car starts and lasts about 3 minutes.
I'll take a pix of by bay over the weekend. Could you take one of your driver side (where the pump should be)?
