sounds like a rattle!! normal?

its been bothering me when this sort of rattle noise occur when I take my foot of the throttle between 2k-1k rpm.. strange once i step on throttle again.. noise seem to be gone? any suggestion? I do have aftermarket DP, innercooler, DCI, and exhaust. Currently running on Cobb stage 2+FMIC aggressive.

eventho i switch maps its still occurs.. hmmmmm?
