I have a 2003 V70 and need to replace the catalytic converter. This is a California model so I need the Cali certified CAT, but I can't find one that fits thus engine, accept for 1500 from the dealer. I found some magna flow cats that are Cali certified, but they do not fit my EFN number. Anyone know where I can get one or if I can install the aftermarket one which is weld-on and be good to go? I do live in Cali, so I want to pass smog.
