WTF Smell??? (Pic Included)

[05GT]

So, the last 2 days or so, I've noticed this odd smell coming from my car. The first time I smelled it was when I was driving. I didn't think much of it, thought maybe it was the exhaust from the car in front.

But then I smelled it again, when on the road by myself. Then once again, when I parked my car and got out.

So now I'm like wtf. So I checked my oil, even though it doesn't smell like an oil burn. Seems fine.

I thought maybe my clutch was going. But then after thinking about it, that can't be it, because it starts to smell once the car gets warm, like if I turn it on in the morning and let it warm up for like 10-15 minutes, it will start.

So today, I briefly check over things under the hood again, then I drop down on the ground take a look under the car and see this on my x-pipe.



WTF is that? I wonder if that is causing the smell, once the exhaust gets hot enough?

I'm at work so I really don't have the time to get into it, but I did touch it and it feels super gooey/rubbery but oddly hard too, and definitely not rubbing off easy.

Sorry but it's a camera phone pic.
