I have a 2002 X type and need to replace one of the cats. The car was originally built to CA emission standards. If I replace the cat with a non Ca certified Cat will I have running issues or check engine issues? Direct fit Cats that are CA carb certified run 900.00 and up and I really do not want to use a universal due to back pressure difference. The car is not in CA. Any help would be appreciated

 

If the vehicle is not registered nor operated in California, there is no requirement for CARB-certified catalysts, but there are sixteen other states that have adopted CARB standards, so it may be a good idea to check with the local jurisdiction.

Installing non-Carb catalysts usually does not cause drivability issues nor the MIL to come on unless there are other issues.

 

I have 2 used ones that only have 80k on them if your interested ? They will be coming off this week.

 

The non-CA cat is actually a better cat than the CA type. As long as you are not in Cali, change it and be happy!

 

That sounds great. Id the obd going to be looking for a higher efficiency than the non CARB cat will be providing? Or do I not have to worry about that?

 

The OBD sees either as being in the acceptable range.

 

If the local jurisdiction does not require CARB-certified catalysts, there is no need to fit them as the vehicle should operate correctly.

Unless there are other issues with the vehicle, the MIL will not come on and there may not be DTCs stored in the system.

 

All vehicles built or sold in this country, after 1995, or when OBDII came into existence were 50 state certified, according to the schools I have been to. Pretty much if you have an upstream and down stream oxygen sensor things should be ducky. If I am wrong, please let me know. I am just a Hoosier, and we just grow corn in Indiana. We used to grow basketball players too, but the recent climate change has wrecked that.....Be cool....Mike

Now you guys just buy them!

 

The California Air Resources Board (CARB) designated more stringent standards than the Federal, or '49-state', requirements. There are now sixteen additional states, including New York and others in the Northeastern United States, that have adopted the CARB specifications. Merely having 'upstream and downstream' oxygen sensors is not going to meet the test requirements.

If the vehicle is being operated in a non-CARB state, there is no need to install CARB-certified catalysts. It is always best to check with the local jurisdiction to determine what requirements need to be met.

 

Check under the hood.....It should tell you. Most manufacturers don't go through the extra expense to make 2 different models anymore. We always had 50 state cars, at least with the German and Japanese manufacturers. By going with the stricter CARB certified emission standards, it assures them of no problems, if other states should adopt them. On the X Type the Carb sticker is on the front radiator core support, at least on my 07. On My 99 XK8 it is located near the LF strut tower. Both cars are Carb certified

 

I believe we are discussing two different subjects here.

If a vehicle, regardless of country of manufacture or manufacturer, has stickers stating that it meets all emissions requirements, that has nothing to do with the test procedures within each state. The test procedures themselves establish whether or not the vehicle will pass, not some sticker(s) in the engine bay.

The OP merely wanted to know if fitting non-CARB catalysts would result in triggering the MIL or creating other performance issues. If the vehicle is operated in a non-CARB state, an aftermarket catalyst can be fitted with no detrimental effects.
