nOT SURE if he answered your question but often times on test pipes you'll throw a code on the computer. Normally it will happen pretty quickly especially when you get on it. From what tony explained to me its due to no back pressure. So 100 miles of driving, hard an normal should throw it. so maybe they got a way to not do it. if so, thats awesome.
Not sure if that was the question??

Any detail on what to do if I ever get this condition would be great, it’s probably already here, I’ll search around for the info

Your check engine light is on because of the aftermarket cats on your car. You have relieved alot of back pressure and the reading from the O2 sensor to the ECU is too fast as well as strong. Without re flashing the ECU the only way to get rid of the light permanently is to slow the reading down as well as minimize the strength it. We have been able to achieve it with the VQ however, the ECU on the HR specifically the G35 sedan is much more sensitive. We are currently working on a fix and Blue, as soon as I have it I will have you come back in to add to yours. Aside of the light your car should be just fine...
Thanks, Tony
