Export a C5 convertible.
It´s possible convert the corvette to Tier 2? What i can do? Change the cat?
thanks to all!


I thought European standards were all the same. The US emissions standards satisfy UK Regulations.
Sorry but I'm not familiar with Tier 1 and Tier 2.

The corvette C5 it´s California Lev 2?


The problem it´s that i need Tier 2, because one corvette tier 1 it´s impossible to matriculate:
"If the car was registered in Spain, before 2006, there is no problem, the car have plates and no problem. All the cars that not fulfill EURO4 (TIER 2 - BIN 5 or LEV II) imported after 2006, coud not be registered to drive in Spain"
But....what about "California LEV - 2", are the C5 california lev 2?

FinnZ06, i suppose that your C5 is a Z06. When did you import it? Germany and Austria have a different regulation for the US cars. I think that the Z06 ist tier 2.
I have these codes:
NA3 Emission System, Japan
NA7 Emission System, European
NB6 Emission System, California, Tier 1
NB8 Emission System, CA/Northeast Emission Override
NC1 Emission System, California, LEV
NC7 Emission System, Unleaded Fuel(Export)
NF2 Emission System, Federal, Tier 1
NF7 Emission System, Federal, Label
NG1 Emission System, Northeastern States
What these codes NA3 or NC1 mean?
I have some problems with english!
