Cali then...
I cant even find anything pre1996 on their website, I must be looking in the wrong section (looking on Aftermarket lookup)

The thing is that it isn't really aftermarket, it is getting it from Porsche themselves. Porsche cats will not be in the aftermarket list

Speedtoys

True, but no more tested on a 928, than an OEM cat off a Honda...so..no pass.

That's used, used is illegal. I am talking new OEM.

Is buying used illegal or using used illegal?

James Bailey

We all have used cats on our cars so using them should be O K .....

Speedtoys

It Depends(tm)

*sigh*

Buying or selling used cats is illegal in Cali.

Using used is illegal if it dosent have the correct stamp (ie no pass). OEM is exempt from that rule.

That being said, all those rules are for aftermarket. Maybe hit up your smog place and see what is their opinion on getting an OEM porsche cat that is from another model being yours is not made anymore. They are the ones passing you or not (ie visual)

Bill Ball

OK, Rich. I remember now you had this from my smog test analysis thread. I'll be in touch.

Bill Ball

I'm game.

Yeah, the CARB website database baffled me too. Magnaflow & Walker are clear, easy to use, excepting the single exhaust boo-boo with Magnaflow. Anyway, I tend to agree that these aftermarket cats are probably not going to hold-up all that long, but it would be nice to have the option. I installed a relatively inexpensive aftermarket cat on my old Durango and it took the awful numbers down to zero. Then I sold the Durango. I don't plan to sell the 928. I've seen 928s older than mine, but with far fewer miles, not necessarily maintained as well as mine, still get VERY clean results. With the high O2 and HC as well as NO, I probably have some tuning issue, but it's not obvious to me what it is. The numbers are consistent with a lean miss.

call some of the texas guys.. they use factory cats for shop wall art....

Is it illegal to transport used cats across state lines?

Mark Anderson

I sold a new factory cat to a Texan and rumor has it he took it off as soon as the car passed testing

CARB has published a list of CATS, companies that make them and their specific application. If the part# or serial# does not apply to the year/make/model of the car it is on the vehicle FAILS the functional test even if it passes on emissions. Ask me how I know... Don't even try a federal cat on a CA car.

This isn't directed at you, Bill, just posting for those that do not realize the police state we live in here in the people's republik.

I'm laughing here, because these stratagems are as if we are talking about underage girls, or guns, or liquor in a dry state. But cats???

I really had no idea it was this hard. I won't talk about my own exhaust because I still had my innocence back then. But now I wonder about the guy I know with an early '80's cat that wants to sell to me. Does HE know we are talking about contraband now? I do....
