Replacing stock catalytic converters on LT1
Has anyone living in California replaced the stock catalytic converters on their C4? I have a '96 LT1 and was thinking of replacing the two stock cats with high flow cats, that will still pass emission tests in CA. Anyone do this? What brand did you go with?
