I've got a 1980 Z28 from TX with a stroker engine and i have to get it smogged in CO. It's no longer any car over 25 years old it's 1975 and older. Which really sucks. I'm thinking maybe buying a cheap cat and seeing if that's all i need to do. Now to be honest i haven't failed yet but i'm pretty sure it will. Does anyone have any tips on getting your 2nd Gen to pass emissions?
