Hi Guys I know I have discussed cats before but they are getting noisier. My car ( as I think all our cars are ) is OBD1. All the cats I see on the net are for OBD2 . Am I just reading this wrong as the comments always say OBD2 cats not for sale in California. I think I have a California spec engine to boot ! Clive Young 95 90S FWD 5SPD
