Hey guys,

So I just recently purchased a 2004 G35 Coupe, I haven't registered it yet because it currently has the CEL on, and I won't be able to pass the inspection with it. The code that comes up for the CEL is P0430, which if you guys don't already know is a problem with the cats. Besides getting a stock exhaust and swapping it for inspection, what would some other options be?

Thanks in advance!

 

You can do a Cat delete and have a tuner tune the code out of the system where it wont pop up anymore. But then again I don't know how they do inspections where you are, because I live in Tennessee and never had to have an inspection.

 

Depends on where you live. If your state/county does visual inspections i would either buy some legal HFC or stockers depending on the situation. But If it's only a plug in test just delete the cats and tune out the cel as previously suggested

 

Hmm, I'll give this a try. I asked a friend and he said deleting the code wouldn't do much as it would just re-appear, but I'll definitely give it a try. Thanks!

 

Thanks, the other person on this thread also suggested a cat delete. I don't know much about the inspections but I'm 90% sure we don't do visual inspections, so again I'll give this a try. Thanks!

 

There is a difference between clearing the codes and doing a code tune. Tuning it will basically reteach your car that, that is how it was supposed to be and it wont ever pop up the code anymore.

 

Do you have test pipes or highflow cats on there now? Look into anti-foulers for the sensors. Much cheaper than "tuning" the code away.
