I need to replace both CATS - california smog, I live in Texas
Ok, I have a code 1416, 420, and 430
Exhaust shop says that since I california emmisions, I have to get different style cats, which are oe, and cost much more!! The way they bolt in is different..
Is this right? The car is registered here in Texas, and stays in Texas, do I have any other options? I was just wanting to put in some oe Magnaflows.. but this is not a option for me?

TIA for helping

No you don't bolt in a universal cat, you would have to cut and weld it in.
$150 for cats and $100 for labor is still way below the price of OE cats the guy is quoting you.
Although unless you replace the whole midpipe, I doubt the CA cats are bolt in also. Do you have the picture of what he printed out for you?

Also, they guy at the shop says, I can put any cat I want on there, but if it is NOT a california emission rated cat, the PCM, which measures from the O2 sensors, is programmed differently than other 49 states, will not measure correctly, and will continue to set DTC codes, not pass emissions etc...

If you want to be 100% stock, find a used OEM midpipe on here. Plenty of people selling them after upgrading to headers and will work much better than some crap he's trying to sell you.

The problem with replacing stock cats is they are ******* goofy shaped. They have bolt on flanges and bends. A universal $100 cat WILL pass emissions but making it fit in the stock location would be a huge pain in the *** (coming from a welder). I've made some cat bypass pipes before but don't know if anyone else makes them available for sale. However, if it was my car and the cats were bad, I'd pull em, gut em, reinstall them, and tune the rear O2s out. Then find a friendly emissions place.

Ok, here goes..
It SEEMS that since my car has a California Emissions sticker under the hood, then I have to keep this in mind when repairing my smog system.
It is my understanding that I can not just use any weld-in convertor for the 49 states.. it has to be a certain type of "high yield" 49 state convertor. Because the PCM is programmed in a way to detect a lower volume of HC, and if I just put on any convertor, I will still pull a DTC.
Am I wrong? Does ANYONE here own a california emission vehicle but does NOT live in california? AND has had to replace a cat converter?
Please help..

CIRCUIT DESCRIPTION
An AIR pump is used on this vehicle in order to reduce the fails pipe emissions during start-up. The PCM supplies a ground to the AIR pump relay, which energizes the AIR pump.
The PCM monitors the HO2S voltages in order to diagnose the AIR system.
During the AIR test, the PCM activates the AIR pump during closed loop operation. When the AIR is activated, the PCM monitors the HO2S voltages and monitors the short-term fuel trim values for both banks of the engine. If the AIR system is operating properly, the HO2S voltages should go low, and the short term fuel trim should go high.
If the PCM determines that the HO2S voltages for both banks did not respond as expected during the tests, DTC P0410 sets. If only one sensor responded, the PCM sets either a DTC P1415 or P1416 in order to indicate on which bank the AIR system is inoperative.
CONDITIONS FOR RUNNING THE DTC
DTCs P0101, P0102, P0103, P0107, P0108, P0112, P0113, P0117, P0118, P0121, P0122, P0123, P0131-P0135, P0137, P0138, P0140, P0141, P0151-P0155, P0171-P0175, P0200, P0300, P0325, P0327, P0332, P0335, P0336, P0351-P0358, P0430, P0500, P0502, P0503, P1133, P1134, P1153, and P1154 are not set.
The engine operates for more than 30 seconds.
The engine run time is more than 20 seconds after closed loop operation.
The engine speed is more than 850 RPM.
The maximum air flow is 22 g/s.
The ECT is between -10°C (14°F)-110°C (255°F).
The IAT is between -10°C (14°F)-100°C (212°F).
The ignition voltage is more than 11.7 volts.
The engine load is less than 40 percent.
The air fuel ratio is 13.125:1.
The engine is not operating in power enrichment mode OR in deceleration fuel cut-off mode.
The short term integrators are monitored while in fuel trim cells 1, 2, 5, or 20.
CONDITIONS FOR SETTING THE DTC
When the AIR pump turns ON during closed loop operation, the HO2S voltage does not go below 222 mV for 0.9 seconds.
When the AIR pump turns ON during closed loop operation, the short term fuel trim does not change more than a predetermined value.
ACTION TAKEN WHEN THE DTC SETS
The control module illuminates the Malfunction Indicator Lamp (MIL) when the diagnostic runs and fails.
The control module records the operating conditions at the time the diagnostic fails. The control module stores this information in the Freeze Frame/Failure Records.
CONDITIONS FOR CLEARING THE MIL/DTC
The control module turns OFF the Malfunction Indicator Lamp (MIL) after 3 consecutive ignition cycles that the diagnostic runs and does not fail.
A current DTC "Last Test Failed" clears when the diagnostic runs and passes.
A history DTC clears after 40 consecutive warm-up cycles, if no failures are reported by this or any other emission related diagnostic.
Use a scan tool in order to clear the MIL and the DTC.
DIAGNOSTIC AIDS
An obstruction in the exhaust manifold may restrict the amount of air flow that is necessary to affect the HO2S voltage. If you suspect this condition, remove the air pipe from the manifold and inspect the passage.
For an intermittent condition, refer to Intermittent Conditions. See: Powertrain Management\Computers and Control Systems\Testing and Inspection\Initial Inspection and Diagnostic Overview\Diagnostic Strategies\Intermittent Conditions

The number below refers to the step number on the diagnostic table.
A check valve that flows in both directions causes heat damage to the AIR system components.

What part of Texas are you in? I have some OEM cats with about 500 miles on them. Replaced under GM warranty at dealership. Price is $150 local to DFW and $180 shipped.
