Illegal Catalytic Converter question...

If it turns out that my Saturn needs a new catalytic converter, a non-CARB approved one costs $50...versus $230 or so for a CARB approved one. (Both are Universal)

Do smog shops actually check (and how do they do it) for CARB compliance on aftermarket parts as part of the pre-smog visual inspection process?

I have access to facilities where I can weld the sucker in myself...not really an issue there...but can I get away with it?

The savings are really tempting.
 
Showing high Hydrocarbons (HC) at idle (only at idle)...high enough to not pass CA Smog Check II.

Have to get prepared...if new OE pre-catalytic O2 sensor doesn't solve it...CAT is next on the list.
 
Usually the CARB approval ID number is either stamped on or riveted on the part in question. The tech will notice that it is an aftermarket cat, but the question is will he look for the CARB ID number. If he is really busy......, maybe not. Some aftermarket CARB compliance parts come with stickers for placement somewhere in the engine compartment. When I put an CAI on a friends Ford PU, it came with such a sticker. I, too would be tempted to do what you are thinking about doing. It's a $50 roll of the dice.
 
The key here is that I now have to find out if the exhaust setup is any different for CA vehicles than non-CA vehicles.

If it requires me to purchase additional parts aside from just a new converter..it may not be worth it.

I always watch what the techs are doing (to my car, nerves, patience, life expectancy) and they never once put the car on a lift to check the cats.

Reminds, me, when you go have the smog check done, you better show the tech that your gas cap is there right away. If you don't do that, chances are that your gas cap is missing and that you have to quickly buy a really junky one from them for $15 on the spot, or you will fail the smog check. This happened to three of my friends within two months. Be prepared for the early 21st century way of doing business!

Must be California.

Such a wondrous state of affairs to be existing in a state where the term "smog check" results in bafflement by the locals since such affairs are not requires here in the cultural backwater. Heck, the locals offer vacant stares of obliviousness about pert' near any term other then "Big Red," resulting in the local yokels dropping to their knees in a worshipping position to devout themselves to the one thing near and dear to their hearts and empty heads.

But, I digest. Uhhhh... regress.

During my multiple decades in California there was always at least one shop that was rather "lenient" regarding the smog check. We had one just down the block from the wrecking yard. Many locals knew that a $10 or $20 tip to the worker led to passing the test.... unless the vehicle was obviously non-conforming, such as smoke pouring out the tail pipe, etc.

Ask around, your area likely has such a firm.

Ask at a wrecking yard or a repair shop in the seedier part of town with mechanics that have trouble with English and/or plenty of missing teeth and/or lots of tattos and/or an obvious lack of personal hygiene. You know.... people from my socio-economic class. The dregs. The scary people.

Don't come right out and ask for the slack facility. Instead, just ask, with a smile, where they would go to ensure they pass the smog test.

Upon arrival, tell the blokes that "such-and-such" sent you.... either the firm's name where you got the advice or the chap's name. It can make a difference.

Give that a try. It worked for us over yonder on the rough side of town.

Happy motoring!!!!
 
Is there a REAL difference between a non-CARB cert cat and "the other one"

..or is that just a penalty that Kalifornians get to pay for having the cat man go through the "baksheesh" process of getting the certification??

Regular opacity meter for oil fired boiler from the manufacturer: $2500
Identical opacity meter that carries the certs (been tested at great expense) according to the PA-DEP: $16,000

Ya what he said. When I install one I have to be sure That I put the #'s down where they can be seen.

I wonder how they ck the #'s on Jeeps that have the converter covered by the belly pan?

Maybe MR.Critic should put the cheap one on then make sure that the underside of the car is muddy on test day. The smog guy will see a converter but wont go dogging to see if it's carb approved and pass it anyway.
 
Put the cheap one on. They'll bend over to look or run a mirror on a pole under the car for a quick check. They only look for numbers if it's something obvious under the hood like a K&N filter.

It's very difficult to cheat Enhanced testing in Cali. About the only way is to put the probe in a different vehicle because the technology used takes the tech out of the testing loop. It's all done automatically and the results transmitted to the DMV then and there. All the tech can do is a visual and operate the car on the dyno according to what the system demands. If he doesn't do exactly what the systems tells him it'll refuse to go further.

The system has interlocked doors and is auto calibrated every day (if it fails it's locked out and reported to the DMV at that moment), on and on. Look at the lengthy design specs for these systems on the BAR website and you'll be amazed at the security. Even the manufacturer's field service people can't access certain parts of the software. Only BAR inspectors can.
 
Wow!!!!

There's been changes in the testing method since I departed the late great once-sovereign state named after Quaeen Califia, according to popular lore.

Still immensely gleeful, pert' near giddy with delight, that we don't have to bother with smog checks or any kind of state-mandated testing.
 
While it may not apply to California cars, in cooler parts of the country, a well warmed(as in HOT) engine often passes when a car that isn't wrarmed up completely fails.
Other 'tricks' consist of a recent tune-up(obvious) PCV valve and air cleaner.
An Italian tune-up(immediately before the test) and fresh gas(87 octane and gasahol) and a bottle or two of stuff that claims to help you pass the sniff test.

You didn't mention model year and mileage on your Saturn, Michael. If the car's eight years or less old with 80,000 or fewer accumulated miles, the replacement catalytic converter is on Saturn Division according to the EPA.

Its 11 years+ old with 96k miles...:(
 
I'd say that he's unlucky. With OBDII you only need to go through the cold start sequence for the internal checks to take place. This is the self diagnostic. It varies from system to system ..but only needs a "good trip". PA's system allows one self "ready" state to be incomplete. Otherwise ..no codes ...you get your badge. California must have the distinction of not settling for the OBDII standard of functionality ..and holding engines to a higher standards then the PCM demands.
 
Maybe the old heat shield can be welded to the new aftermarket cat, making it look like an old catalyst that happens to still be working really well.
