So a buddy comes to me and tells me he has a problem with his car. No big deal right? Well pretty easy to figure out he needs a new cat not a problem. I ask him the info of the car he says "2005 2.4L PZEV".... this is something that is new to me and looking into it seems to me until I never move to Cali will never be an issue for me. The problem a cat for one of these is about 6X as much as it should be! I guess my question is is there any way around this can we just put a regular (normal) one on with out having any issues? PLEASE HELP!
