I used binder clips to clip some of the loose pieces in the bumper and found a nut missing holding a shield attached to drivers frame.

Suggestion
Thus have you dropped the oil filter and poured its contents out in a *clean* drain pan and given the oil a thorough check for any scary metal (or other material) debris?
Leading evidence: 'Use binder clips' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Check any scary metal (or other material) debris' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.
Source reports, not a diagnosis or a success probability. Counts refer to discussions and can overlap.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

No possible source jumps out at me. This leaves oh about a zillion possible sources though�
Wish you could have just let the engine idle.
You are at the vehicle so let me ask you the questions. Do you have any idea where the noise is coming from?
It would be worth the cost -- and some places do not charge for this -- to get the car in the air and give a listen under the car and pinpoint where the noise is coming from. If this can be pinpointed and it can almost 100% of the time this goes a long way to helping ID the source/cause of the noise.
However, I'm reluctant to suggest you should run the engine any.
Thus have you dropped the oil filter and poured its contents out in a *clean* drain pan and given the oil a thorough check for any scary metal (or other material) debris?
Does engine exhibit this noise immediately upon a cold start? Or does the engine have to idle a while before the noise comes up? Or does the engine have to be fully up to temperature before the nose appears?
Does the noise change if you depress the clutch or if you put the Tip in gear?
If the noise is present with the engine cold you can remove the belt and start and run the engine long enough to verify the noise is present or not. What you hear or do not hear determines your next step.
Be sure you note very carefully -- take pics or make a sketch, and take notes do not rely upon your memory -- the routing and direction of rotation of the belt before you remove it so when you reinstall it you install it correctly and so it rotates in the same direction as before.
While you have the belt off give each accessory drive pulley a check for excessive play. Really though my experience is any play. If there is a problem with one of these you will know probably because it has some play while the other accessory drives have none.
Check the idler roller bearings and tensioner roller bearing for any signs of distress. Too much play. Signs of a compromised seal.
Here is a better video.
The sound comes when I give gas. 1000-2000 rpm range. Sounds like something is rattling when the engine increases rpms.
996 rattle 3 - YouTube
I just did the oil change and I tore apart the filter and it looked complete clean on the inside.
The next vid, I let the engine idle a little. It does not make the noise while idling.
When I did the oil change, the rattle came from a loose clamp at the cat and I tighten that down. That rattle went away. I guess initially it was a combination of rattles.
Get someone to help you give gas. Put a long screwdriver between your ear and each cat. Sounds like cat rattle (core inside broken) or muffler shield rattle to me. Sounds external but it's not easy to tell from the video.
If not those, just follow Macster's suggestions above.
The easiest check is on the heat shield. On a cold engine feel in for a bolt attached each end. If the far one (out of sight) is missing then it could be a loose heat shield. The noise to me is giving off a (tinny sound) and the heat shield over the Plugs is very light weight in nature.
I did make some progress. I used binder clips to clip some of the loose pieces in the bumper and found a nut missing holding a shield attached to drivers frame. Then I shimmed one of the clamps holding the cat to the engine. Now I have some not so loud rattles at 1500-2000rpm... ugg. This all started after I took the car to have an safety inspection done.
I'm also gonna go with something in the exhaust. I would try taking it off and run the motor to see if you can reproduce the noise. What the hell crawled into your garage at 42 sec into the video?
On another thread I was taking some pics of the underside and Ahsai pickup up the fact that I was missing a stud. Great find. Hope that will fix the problem.
I would soak it with Kroil overnight and try to punch it out. Apply some heat if needed. Maybe tough to punch it out in-situ though. The gasket at the joint should also be replaced once you separate the header and the cat.
This is a source reference. Confirm exact model applicability in the original material.
