Okay so I have a question that hopefully can be answered on here, my 2015 Nissan NV 2500 HD has a California emissions sticker under the hood. But I live in a federal emissions state of North Carolina the cost to replace my catalytic converters would be drastically cheaper if I bought them and installed myself the problem is I have heard that since my vehicle for some reason even though generated in Canton Missouri having a California emissions computer installed would reject any catalytic converter that did not meet California emission regulations which is very disappointing being that I have nothing to do with California and never will. So the question I would like to ask is has anyone ever installed aftermarket catalytic converters that will pass Federal emission standards on Nissan vehicles which I have been told were all set up for the 50 state converters I hope that this can be done any input from anyone even from Nissan themselves would be greatly appreciated
