I also have the rattle and it seems to an internal issue. Probably the internal flap that opens and closes to increase or decrease pressure thus changing the sound characteristics.

I have been getting an exhaust rattle at certain RPMs. I checked the band that holds the exhaust to the motor and it is tight along with all the other bolts holding the exhaust to the header.
