Great to see another boosted NC Z! We have had no issues with inspections with the cars we have done. The 2012 Nismo we did with the GReddy twin turbo kit passed inspection at the dealership with no problems. With no CEL they don't have much reason to lift the car in the air for a visual inspection of the catalytic converters.
All-in-all the inspection process isnt to stringent in our area yet. Most shops wont hassle with getting the car up in the air for the visual exhaust inspection. Plus most of them wouldn't even know what they were looking at, haha.
Thanks,
