I could do cat back I just haven't looked into it and I don't really know that much about them. I'm new to all of this car stuff hahaha also I live in CA so I need things that has a EO number that can pass emissions
I THINK anything cat-back is A-OK and not subject to CARB/EO rules. You can't mess with the cats, though. If you need to replace them, or even add headers, they do require CARB stamp.
