Basically, would it be a problem to replace both of my 996 113 022 93 with 996 113 022 97.

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.

I need some ideas on what this is that is blocking my exhaust. I've been looking at lots of images of Cat and Muffler internals and this to me seems like its something from the cat.
The piece is metal and I can't pull it out or push it back. Its jammed in there pretty good right now, but I'm assuming that once the tips are removed and exhaust dropped, it will be easy to remove.
Any ideas?
Thanks, that's what I was thinking and that's the feedback I've gotten from some other sources as well. Does anyone have any photos of the internals of a 996 cat? I'm curious as to how its setup.
It is basically what you see there. It will look like a flat wall of honeycomb. Take a screwdriver and chisel that down to chunks and blow it out of your exhaust with a couple blips of the throttle
Aftermarket or not would have no difference on how a cat element can get blown into a muffler and somehow accurately positioned again to exit out another tube within the chamber(or chambers).
Edit: Actually I can see it if the muffler inlet is one continuous perforated tubing going all the way to the exhaust like below:
OP, you have aftermarket cats too?
I had resonators on a 914 one time that had a substance like that just out of view from the exhaust tip. One came loose and moved on down and looked very similar.
I have stock cat, but the part number is 996 113 022 93 for the European MK1 GT3.
Does anyone know the functional difference between 996 113 022 93 (for M96.76) and 996 113 022 97 (for M96.79). Basically, would it be a problem to replace both of my 996 113 022 93 with 996 113 022 97. Would I see any performance hits/gains and or other issues.
Sorry to see that! If you need a new set of cat pipes or a catted X-Pipe, we can help get you up and running.
Just email or PM and we can get you your 6speed member cost...
haha...i don't want that guy anywhere near my car.
So even though my cats are mk1 gt3 parts, the internals have been completely modified by ruf to be 100 cell. Spoke with ruf and will need to send to germany for a proper rebuild.
In the meantime, i'm planning on going with a cat bypass xpipe for a temporary solution.
Well unless you don't have to worry about emissions in your area or future resale, 200 cell cats will do a better job of filtering, less chance of CEL light coming on, and will only be marginally more in cost to the 100. 100's almost always sets off CEL's in our finicky systems unless O2 extenders are used. In Germany where RUF comes from, 100 cell cats may not be a problem over there. Also their ECU's have different operating parameters over there.
I don't have to worry about that since the car has had the 100 cell from factory since new. Has never thrown a CEL and passes inspection without issue. As for resale, i think rebuilding them to their original specifications is better than making modifications. Hopefully wont need to sell for a long time if ever.
Hmmm, not really sure I understand. The factory cats have 2 sets of cat elements on each bank and they are closer to 400cpsi.
Aftermarket usually only consists of 1 cat elements on each bank and is 100 or 200.
I don't know what your readings are but 100cpsi elements are illegal in some areas since they can't meet emission requirements.
What i meant is that the car was built with and shipped with the 100 cpsi cats from ruf for the US market and has had no problems with CEL or passing inspection. Thats why when the cats get rebuilt, i would prefer them to be rebuilt to their original specifications.
I'm not sure if RUF was specifically built for the US market or came over as a gray market item from certain resellers. All I know is their products would've been technically illegal to sell in some areas.
Either way if 100 elements works for you, more power to you.
Is it even cost effective to get them rebuilt over there? Or do you want to stick to the RUF brand?
its not cost effective, but its the only way they will rebuild the cats and I want to stick to the brand. Ruf will be partnering with a California company shortly (early next year) and I'll see what my options are at that point for the rebuild or if it makes sense to just replace the parts with new ones.
