3 days ago i installed 2 new catalytic converters on my car and i looked at them today and there turning like goldish do you know why this can be? is it normal? i have a 93 j30 infiniti with 110k miles.
Answer:
That means they are working. They need to heat up to very high temperatures to function properly. The coloration of the metal is the material being altered by the extreme heat, and is normal with a catalytic converter.
