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.

Any idea where is the best place to buy a stock or replacement Cat Converter for a 2002 996 C2? Just 80k km and the right cat started to rattle.
Any help would be appreciated.
By right side I assume you mean passenger side? Oh well, this is for a driver's side just in case. Too bad it's not closer....

Porsche told me that the emissions warranty will not replace a cat simply due to rattling.
One of the local dealers here in Atl. thought a rattle I had was a cat (resulting in the above statement), but it was actually an interior rattle in one of my PSE cans.
My other PSE can is now beginning to develop the rattle as well. Damn it.
I've had both cats replaced in the past 18 months due to that rattle. Fortunately, they were covered by the CPO program. The stealership charged PCNA over $1800 EACH time.
It is under warranty. I just have both of my replaced at 49000km. The emission warranty is 12X000km or 8 yrs in Canada.
If there is no cel code, dealer cannot replace under warranty. Just keep driving it, the cel code will come up. In my case, the cel lighted up approximate 1000km after they rattled.
New Cat at Sunset is around $800. DIY is pretty easy. FYI

Huh, here in So. Cal is easier to replace by the dealer. Last year, my left cat rattled and no CEL so I brought the car to my local Porsche dealer for check up because the noise bothered me. Service manager advised to replace the bad cat. He replaced both cats. Fed laws no charge. Went home with two brand new cats.
Sounds like you're still under warranty. If not, my dealer said $1300 to replace my driver's side Cat (was rattling and throwing CEL). I spent 1500 (1600 or so with install) and got both Fabspeed Cats instead. It was a good ten to fifteen pounds less and sounds a lot better. Plus, don't ignore that rattle. My Cat threw crap into my muffler and it had to go too... (spent about 400 to replace with another used stocker). So if its under warranty (or not), make sure it hasn't sent pieces into the muffler also.
Just FYI. This was on my 01 C4 Cabrio.
I've had to replace both cats on mine. Both times it rattled first but as others have said I had to wait for the light to come on before the dealer would replace under warranty. It sucked, but I drove around with them rattling rather than pay out of my pocket. Lights came on shortly after the rattle started fortunately.
Don't know for sure. Probably not. If the converters are part of the engine's exhaust manifold the manifold is sized to the engine's exhaust port openings and a the 3.4l exhaust manifold will have smaller tubing size than the 3.6l exhaust manifold.
One round about way is to get the VIN for 3.4l car and the VIN for 3.6l car and visit your local Porsche dealer parts department and have parts department look up part number for the converter for the 3.4l car and the converter for the 3.6l car.
If part numbers are the same...
Odds are they will not be the same.
Another way would be to take a peek under a 3.4l engine and under a 3.6l engine to note if there are any visual differences. If so, odds are the converters are not interchangeable.
Sincerely,
Macster.
