Weird Little noise at 2K RPM when Throttle Released

[1cardude]

When I am at a high RPM's and then i totally lift of the throttle, my 2003 Maxima (SE 3.5L V-6 106k miles) make a funny noise when the RPM's drop to 2k.

So lets say i accelerate hard then totally lift from the throttle...when the RPM's hit around 2k there is this weird clinking, stutter, rattle noise? I dont know if it is the throttle body, or the exhaust manifold or what.

Any guesses?

It's probably heat shield noise, but hard to say for sure without actually hearing it.

check the small bolts that hold on the manifold heat shields!
