Reported cause
I had the same issue and mine turned out to be a weld inside the tip that broke loose.
Leading evidence: 'weld inside the tip' (1 discussions report identifying this cause; no attributable repair resolution). Across 1 matching discussions, the most frequently mentioned possible cause is 'weld inside the tip' (1 discussions; 1 report identifying it and 0 suggest it). The most frequently discussed action is 'Check install' (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.

I had a similar rattle on my 02 after installing PSE (and tracking the car) and the dealer replaced the cats under warranty

We replaced all these clamps and the rattle is now gone.

Suspected cause
I am still getting a bit of a rattle if I purposely lug the engine, but at least the problem is more or less resolved, although I would not be shocked if it comes back.

I have checked the install to ensure everything is tight but perhaps I am missing something.

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.

And when I got to the bracket that connects to the left exhaust tip, that did the trick.
I have recently installed a used PSE system and have a rattle which, if possible, I would like to remedy. The car is a 1999 996 C2. The rattles are at low RPM (idle-2.200) and are somewhat intermittent. I have checked the install to ensure everything is tight but perhaps I am missing something. Worse yet, perhaps the system is bad - although I have to say the sound (above 2.200) is AMAZING when compared to the previous (non-rattling) stock system. Any thoughts or suggestions are certainly appreciated. Thank you.

Hmmm...I hope you didn't buy a bad 'used' set. Can't think of anything other than taking them off and shaking them to see if the rattle is internal or something loose on the outside. It has to be the mufflers since you did not have the problem before. GL and keep us posted.
i had a similar problem on my '03 c4s though my PSE had come with the car. I experienced a low speed rattle especially when making turns. The dealership traced the problem to rusting and loose clamps that hold the exhaust in place. We replaced all these clamps and the rattle is now gone. Another issue could be the components inside the cats are coming loose - you can test this by tapping the cats gently with a rubber mallet. (be gentle - don't hammer away at the cats)... if you hear things moving about inside, then you may need to replace the cats :-( Hopefully its just the clamps which cost far less to replace.
I had a similar problem on a Mk1 PSE. The actuator arms that open/close the valves are nortorious for loosening up and rattling. They are pressed together, not bolted. Spray some WD40 on it. The other thing is the litle heat shields get loose and will rattle or sound like a empty beer can.
My right side PSE developed a severe rattle when hot.
When off the car and cold, shaking it would not produce the rattle.
Cats do not just "go bad" and develop rattles. Poorly tuned engines can damage cats over time.
I have read of other PSE failures as well.
It sucks as these mufflers are far to expensive to fail in only 20k miles as did mine.
Our 2004 C4S cab with PSE developed a very loud rattle at idle, although the rattle would go away after the exhaust system was fully warmed up after driving several miles. If I put my foot against the left exhaust tip, the rattle would stop, so I assumed it was something to do with the tip or something connected to the tip. But when I got under the car, I had a difficult time figuring out exactly where the noise was coming from. I started to tighten all the exhaust brackets, several of which were more loose than I would have expected. And when I got to the bracket that connects to the left exhaust tip, that did the trick. I did notice that this bracket had quite a bit more rust on it then the others. I am still getting a bit of a rattle if I purposely lug the engine, but at least the problem is more or less resolved, although I would not be shocked if it comes back.
