Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

on the original question, I had done a bit of research on the topic and although I couldn't find a definitive answer, my understanding is the both EU and US cats fitted on the 996 are 3-way cats but the metal composition of the cat itself is different, due to legislation constraints.

There are quite a lot of used versions available, but many different part numbers.

Coverage and how to read this overview

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.

POST 1 / ORIGINAL POSTEROriginal post

Hey all, I have a US (California) 3.6 996 C2 (2004), which I have imported to Germany Problem is, the catalytic converter has totally failed, and I need a new one. They are $2k EACH from Porsche in Germany, and none of the aftermarket options will pass the T�V (it has to be an original Porsche part.) Even amongst new ones, there is a big price difference: 99611303102 costs �1750, while 99611302112 only costs �1050. There are quite a lot of used versions available, but many different part numbers. Does anyone know if they are all compatible? What's the difference? I am trying to see if there is a (used) cat here I the EU that will fit on my car. I think only OBDII cars have two O2 sensors (pre- and post-cat), correct? But beyond that, are there any differences, or are they all the same thing basically? Here is the full list from the German porsche site. As I understand them, parts 21 and 22 are just the left and right side of the same part, respectively. So eliminating duplicates, the list is: Here is a different list from the US parts catalog And here is another list from the EU parts catalog:

I'm not sure how much lax German emissions are but another option since you're already in Europe is to have Gert at Carnewal rebuild your cats with cell 200 cat cores. http://www.carnewal.com/products/P96...-to-Sport-Cats

Wow, I had no idea that option was out there, thanks!!! I'm writing them immediately!!

POST 4Original post

didn't know about this either - I wonder if there is someone doing the same in the US? on the original question, I had done a bit of research on the topic and although I couldn't find a definitive answer, my understanding is the both EU and US cats fitted on the 996 are 3-way cats but the metal composition of the cat itself is different, due to legislation constraints. Here is from the 996 buyer's guide: Reason for researching this is that 3-way catalytic converters need "help" from the ECU to stay clean and not wear prematurely. I am still not sure if the ROW tune is compatible with US cats or not.

This is a source reference. Confirm exact model applicability in the original material.
