Rattle on the down rev...
#4
My car was doing the same thing and it was the mesh inside the rear bank precat that came loose.dropped it,gutted it,all set now.Try to get it on a lift and have someone under the car chase the noise while you keep the rpm's where it makes the noise the loudest.

Had the same rattle, was bank 1 (firewall side) pre-cat. Remove (need to order new gaskets) and inspect. If the catalyst material is loose, that would account for the rattle sound on down rev.
You can pick up the pre-cat from Nissan, discount here http://forums.maxima.org/8272195-post22.html, and be sure it'll fit and take care of the problem.
Also can get headers and the o2 simulator.

Might be your valves rattling. do you have an oil burning issue?
I burn oil at a good clip in my 03...come the 2000mmile mark after a change i get an obnoxious rattle from the engine bay and its the valves. Never happens after a fresh change or if i top off the reservoir.
Try checking you oil levels

Costs nothing to remove the pre-cats and inspect. You'll only need the gaskets but probably can take the chance and re-use them. DaveB told me people spray the copper gasket over exhaust gaskets and re-use them.
You'll know you need the pre-cats if the catalyst is loose in the housing. When I replaced my known bad pre-cat, I felt the engine respond BETTER. Then I did the other pre-cat and again noticed a slight boost.
