Motor vehicles 25 years old or older: Vehicles that are 25 years old or older must undergo inspection for safety and emissions. However, these vehicles will not be failed if they do not pass emissions standards.
Right so...how old is it? 2017-1993 = 24. Is that how they judge? I guess that means the next sticker is the last real test so summer of 17 swap is possible.

Its also possible that a stock LS would pass emissions for a '93 L05.

That STS in Fall River is the one. I like these. I was just saying this weekend I should swap the 3 for one. Even money.

Yes, stock, definitely. Except if they become wise to the transplant, I could have to go down that road of showing what it came from so I can pass THOSE emissions. I guess I didn't want to deal with that after having done all the work. Now I won't have to.

Ugh, alarm? Like an aftermarket one? WHY?

Low catalyst efficiency. Could be an O2...or could be a cat. At the mileage, I would bet on the cat, unfortunately. I don't think this is a particularly easy job on these cars, either.

Rockauto research reveals a few things.

First, it uses an integrated exhaust manifold/cat. I don't know what kind of gymnastics are required to pull the manifold but it could either be easier or harder. Easier because separating the cat from the manifold is usually the sucky part of the job and these are made as one piece. But it could be worse in terms of getting access to the manifold (could have to jack the engine off the engine mounts or other horseshit). I will consult my FSM when I get home. It won't be pretty.

Second, the part alone is $223 to $300 per side. Not terrible. But they all say not for CA emissions. I'd bet this car has CA emissions assuming it was sold in MA originally. Who knows how much the OEM part actually is, since the aftermarket companies don't see to claim compliance.

On the other hand....HP Tuners or EFI Live could be an option here, once you start adding up all these costs.

Side note, I do like the 08 redesign, but the unloved first gen is likely the one in the budget.

Some info. Not that it can never be fooled but he specifically says that all O2 diagnostics must run AND pass before running the catalyst efficiency diagnostic. Like I said, I'd bet that it actually needs a cat.
Problem number two is... a bad O2 sensor will not set a P0420. A bad O2 sensor will set a bad O2 sensor code. P0420 indicates that the O2 sensors are in fact good and the catalyst is not doing it's job. The O2 sensor diagnostic tests MUST pass before the P0420 DTC diagnostic will even run. If the PCM knows the O2 sensors are operating properly and the test enable criteria are met the P0420 test will run.

These conditions must be met in order for the diagnostic to run:

No TP sensor, MAF sensor, MAP sensor, IAT sensor, ECT sensor, HO2S, HO2S Heater, Fuel trim, Misfire, EVAP System, EVAP Control, VSS, or Idle Speed DTCs are set.

• Engine speed since end of last idle period is more than 800 RPM for 46 seconds.

• Idle period is less than 180 seconds (3 minutes).

• Actual engine speed is within 100 RPM of desired engine speed (Non-California)

• Actual engine speed is within 125 RPM of desired engine speed (California).

• Engine run time is more than 7.5 minutes.

• The predicted catalyst temperature is between 420°C and 650°C (788°F and 1202°F).

• BARO is more than 75 kPa.

• ECT is between 71°C (160°F) and 120°C (248°F).

• IAT is above -6°C (21°F).

• Engine is in closed loop fuel control.

• Tests attempted this ignition cycle is less than 12.

• Test attempted during idle period is less than 1.

GM list on each manifold/cat is about $1000 (what is this, a German car?). Could get like $200 off or so buying from a cheaper source but that's still $800. And based on research, if you really want to be sure it passes the diagnostic, you need the OEM part. In that case, it would probably be cheaper to just turn the code off with some software. Go on...

HP Tuners does not support the 05-06 4.6. Nice. Checking EFI Live...
