The exhaust pipe rubbing against the underbelly would be my guess.

UPDATE!!!!!!!!!!!!
so my friend came over and we were poking at everything seeing if the noise would stop. then he was like try revving the enigne a little, so i did and a chunk of something flew out of my exhaust!(see picture) is this piece important and what is it? i guess it was just rattling around in my exhaust pipe.

oh ya and after that flew out i started it up again and it wasnt making the noise so that chunk is what was making the noise.
