They require cutting and welding and need the mid-cat O2 sensor to be installed somewhere else.
Leading evidence: 'Install somewhere else' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Check (meaning visual, functional and emissions sections of the tests)' (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.

Ream it out good to get the aftermarket cats hot and make sure it is tested while hot as apposed to cold.

I have not gone through any smog test yet with them but I hope they will pass the pipe test.
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 read that thread a few minutes ago and won't be buying from them! Lol. Does anyone know if anyone has any info on any ca legal cats that are now legal in ny. Or would I have to do the yearly switch for inspections? That's kind of ridiculous
I'm not sure where you get "yes" for the 993 out of that thread - but it's a NO.
Nothing but stock will pass a CA smog check (meaning visual, functional and emissions sections of the tests).
No carb sticker on Fabspeed cats. "You may pass emissions testing" is definitely not the same as "you will pass visual inspection."
Sorry, Nexus, wish the answer was better.
Not true, a CARB approved replacement cat will be legal.
The thing I've found about getting my 4 often highly modified Porsches smogged here in SoCal during the last 20 years is that not one tech has got on his hands and knees to see what the exhaust system is. Its always plug and play with a glance in the engine bay.
One trick to passing the emissions test is to have that car hot and bothered before the test. Ream it out good to get the aftermarket cats hot and make sure it is tested while hot as apposed to cold. A cold start on aftermarket cats may fail as they often take longer to heat up therefor failing the cycle time.
This was ALWAYS true for me until I was "selected" to got to a "Star station" this year. There were flashlights, kneepads, mirrors on sticks. I definitely do not approve.
This will allow you to search for CARB approved cats for your Porsche.

Note; I do not endorse, or support any part of the search process, nor do I own or operate or smog any cars in CA. YMMV, don't blame me if it doesn't work. I found three mfg that have a CARB approval for various years.
Ok, if what I said is not true, please tell us which replacement catalytic converter is currently available that is CARB legal?
Of course, in theory, a CARB certified "anything" is legal...
Don't waste your time, guys. I'm not aware of ANY for Mk I 996s. For MkII 996s, the ONLY carb certified cats are these (red text)
http://www.discountconverter.com/dir...&CylSelected=6
I hear you. Not that it helps a lot an OE cat is ~$1,700 EACH available from Sunset Porsche.
Would be nice if someone has installed those carb approved cats could chime in for their experience. I've asked a while ago but got no response from this forum.
And if you read the actual executive orders, the CARB compliance can be revoked for numerous reasons. I wonder if that means if you spend your money on so-called CARB complaint cats, and they lose compliance because they stop doing their quarterly monitoring and semiannual reporting or whatever, you then need factory ones anyhow because your product no longer has a valid certification! Uggh...
I guess there's a lot you aren't aware of.
Have you done all the exhaust flow measurements? Do you know what the spec is from Porsche for the OEM? Do you know how it compares to the magnaflow?
Yeah - thought so.
Thanks for asking so kindly. Nope, I have not done such testing. All I've done is read the link you posted which would concern me putting on a universal cat that is applicable to a Geo Metro.
I assume from your comment that you have this information to enlighten us? I always enjoy learning stuff.
docmirror, not clear from your post whether you found something or you're recommending it. By all means share with us if you have good experience with those universal cats and recommend them.
So, $350 per side sounds pretty tempting.
I see on the CARB site that Valina is the only company authorized to manufacture aftermarket cats for the 996.
Doing a quick search it appears Magnaflow, Discountconverters and Valina are all tied in to Valina as the manufacturer although the Magnaflow converter seems to be a generic offering.
Paul
The Valina ones are generic 2.25" inlet/outlet, 4" diameter in 8", 9" and 12" lengths. They require cutting and welding and need the mid-cat O2 sensor to be installed somewhere else. $250 each.
There's no info about the cat density or cell size that would affect flow characteristics... but maybe docmirror has that information for us.
Get the ones like Ahsai did from Carnewal and call it a day. Don't really know why you guys are exerting so much effort on this. Oh, I know, because Rennlist...
Thanks! I find it ridiculous that there's a visual inspection when you are actually passing the emission standards! They don't use the sniffer on obdii cars in ny.
Thanks for posting this. $1000 for stock garbage that doesn't even work as well as aftermarket. Ridiculous. Only good thing is that cars 1993 or earlier are exempt from this stuff in ny.
They changed he law in ny so that only carb approved cats can be used. After looking at carnewal, that might be an option! Do you have to send it all the way to Europe? Or is there an American distributor?
All the way to Belgium. Cost me ~$1200 shipping included (~$160 to ship both cats to them)
I have not gone through any smog test yet with them but I hope they will pass the pipe test. Will update my thread next yr when the time comes. Appearance wise they are identical to stock.
The lobbyist have to get paid to push for various laws in the great country we live in. Then there are the kickbacks...
Unfortunately none of these people are enthusiasts of cars, only money.
Some probably are car enthusiast but they get their stuff under the table. For instance in ny you "need" to have a front plate. The nassau county executive was at a car show with his 71 corvette convertible with no plate. And he had two detectives as bodyguards. Double standard?? I think so.

Suck not pass for 993 just fail to day 15-25 miles over fail � need do special 350$

Does anyone know if fabspeed or any other aftermarket high flow is carb certified? Ny adopted the same stupid law as CA...[/QUOTE]
