Hi guys,
A couple of weeks ago I threw the P0420 code on my Jeep. To fix this, I decided to buy all new o2 sensors (NGK) and catalytic converters. I bought the Magnaflow (447188) CA-compliant catalytic system. Do I really need to buy the third rear catalytic converter to pass smog in CA? The cheapest rear catalytic converter C.A.R.B. compliant bolt-on one I've found is over 600 dollars.... and it's Walker. Thanks in advance!
