Hi, sorry if this has been discussed before but I haven't had any luck searching. I have an 03 vibe gt registered in California and I need new cats but I'm having trouble figuring out which to buy. I know the AWD is completely different but the pics I've seen make it look like the base 1zz and 2zz use the same cats but I don't know if the internals are the same, especially with it being a CA car. I've been doing compatibility checks on various sites and getting conflicting results.
Before I drop a lot of money, does anyone know if the cats are the same or if I need gt specific ones?
