Hi there, so I got a 2014 mustang, and I have been looking at this x pipe with high flow catalytic converters for a while, I like the difference it makes in the car since my friends have one in theirs. I just had a question about this I couldn’t find anywhere in the American muscle page. If I install these and I get a smog check on the car, would I pass it? I’m not sure if it’s CARB legal, and if not, will it not allow me not pass the smog check at all? Or does the CARB not matter when...

Will I pass smog check if I install a x pipe with high flow catalytic converters?
