They used a popular generic high flow cat, welded it to a pipe and a flange, attached it to the one side of the header outlet and then ran the test, passed me, and then installed my test pipes again

I was surprised how much the tone changed considering that I was already running headers and their mufflers.

I run catless with a fabspeed supercup exhaust and it's waaaaay quieter than my NSX and viper were without cats.

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.

Today started out a little crappy, long story short I found out I need a new catalytic converter. The Porsche OEM part is around $2300 per side (och) but I only need one, for now. Now i'm trying to look on the bright side by using this as a push to upgrade the exhaust, cats and mufflers.
I'm looking at Fabspeed right now, are there other options I should be looking at? Does anybody have a setup in their garage they want to sell? I have a 2002, 996, C2 cab if that matters.
In talking to my service tech he said the old cats could be worth a few hundred each in salvage, is that true? If so what should I except to get for them?
Thanks
interesting question about how much they are worth when 'broken'...
I assume the 'cartridge' in them can be fixed
I also have a broken one and a good one. I upgraded for the high flow cats, better sound anyways
i was all about replacing the cats before learning of CA and the great state-evil empire's BS not allowing anything not having a C.A.R.B. stamp on it. (which no after market company is doing that i can find) i have seen several cats, left & right OEM on EBAY for 2-$300 a piece that were for a 996. That fabspeed x-pipe is hot, too bad i can't use it. I found another x-pipe made in Germany that was supposedly 200 cells instead of the 300/400 cells in the stock for $1k, same BS...can't use it either. Keep looking u will find different cats. good luck!
There are CARB catalytic converters. Did a search on California's Air resources board and they have a database for Porsche 3.6 converters. I haven't called the manufacturer but it's a start. What I wonder if this can fall under financial struggle and get some $ from the state or some kind of exemption. Since ive gone through5 sets, I rather investigate this route.

Original Porsche cats are worth up to a couple hundred dollars each at metal salvage yards. They have a high content of precious metals. I have sold several 944's cats from dismantled cars for very good money.
Here's some used cats for sale locally. You can do the swap yourself in the driveway in literally half an hour with regular hand tools.

I saw that, it's just a crap shot as too weather they work and if so for how long? It still blows my mind that the OEM part is $2000+.
I've been flirting with the idea of going to fabspeed mufflers, this would just force me to go with their cats too.
It's a good excuse to go with a high-flow setup. Our emissions are easy here in Washington, so no need to worry about that aspect. As long as you don't have a CEL you pass.
No it does not mean that. I am only responding for Cargraphic and AWE products not FabSpeed. And your Indy shop is correct.. There is an ~8 week wait for AWE as they are made to order.
If the cat is clogged, it can be hard on the engine. If the cat is bad for some other reason and flowing properly, it's not going to hurt anything.
You sure the cat is the issue and not your secondary O2s?
Headers, cats and Fabspeed mufflers, sounds great to me. I was surprised how much the tone changed considering that I was already running headers and their mufflers. It is difficult to describe sound and I will call it metallic. It is also louder as soon as you are off idle.
opps just saw your sig
sounds like a nice set up. I don't have the coin to do the whole thing right now was thinking about doing the cats now and the mufflers in a few months.
I'm on the fence, a tech I like at my dealer said Fab speed all the way. Meanwhile a good indy shop said AWE is the only way to go.
Are these 200 cell cats guaranteed not to burn out at the track? Some tracks have sound restrictions and well, I think the 200 cell cats and sport exhausts will be too loud
Are there any aftermarket cats that will pass smog in California? My left cat is going out too (probably will get some more life out of it but starting to rattle).
I was worried about my car passing the sniffer test here in Ohio. I have Switzer exhaust and hi flow cats on my TT. The kid took a mirror and ran it under the drivers door looking for the cat and inspecting the exhaust. It passed with flying colors. I'm sure it would've passed even if he would have known where the exhaust was located. I didn't have the heart to tell him he was no where near the engine or exhaust. Even though I really wanted to ask him how he liked the exhaust.
When I lived in SoCal a few years ago I had always run test pipes on my NSX and Viper and I will do the same for my 996 when I move back in a few months. Screw cats, they ruin the beautiful sound our flat 6 motors! If you want to run test pipes or high flow cats then do it, there are EASY ways around passing smog tests and it won't cost you that much. This is legit too, no bribes or shady stuff involved. My "exotic car friendly" muffler shop/state certified smog testing center in San Juan Capistrano custom made me a cheapo brand new catalytic convertor that had the stupid "carb" sticker. They used a popular generic high flow cat, welded it to a pipe and a flange, attached it to the one side of the header outlet and then ran the test, passed me, and then installed my test pipes again
All in about an hour! All legit eh? Technically you pass the test so there are no issues. There are ways around CA's stupid smog laws as you can see....... Also I know a LOT of smog shops that ignore "carb certified" requirements as long as you pass you pass..... PM me if you want the hookup.
Also I wouldn't worry at all about getting caught with high flow cats or even test pipes after the fact. Cops will never know what kind of cats you have, and even if you have test pipes our 996's aren't that loud compared to other cars. I run catless with a fabspeed supercup exhaust and it's waaaaay quieter than my NSX and viper were without cats.
