What year Corvette do you have? The 2002's are 50 state legal so the emissions are the same for everyone. Previously, in 2000, you got a pair of extra cats. I believe in 2001 everyone got the extra "pup" cats. If the material in those "pup" cats were to somehow fall out, you'd see a slight performance increase...IMHO

I have a deposit down on an 02 Z06. I was noticing the options on a car from a dealer in the Northeast and the options on a car not from elsewhere and caught that the one for sale in the Northeast has listed option NG7 - Federal Emission Override and
NG1 - Northeast States Emission Requirements.
I am trying to find out if that is just admisitrative or if there is actually a difference in the cars.
