MagnaFlow 447205 California Grade Universal Catalytic Converter, 2.25" Inlet/Outlet (CARB Compliant)

I replaced the pre-cat a/f sensor twice. Once with a bosch sensor which failed in a year (CEL came back on) so I replaced it with a Denso and the light came back on once the OBD readiness cycle was completed. I did not do any other repairs until it was time for a smog inspection (California). This replaces the rear catalytic converter and solved my P0420 code. You may want to replace the front one also because if it is bad, it may contaminate the rear one.

This was a perfect replacement. If you’ve welded and cut metal before you can probably do it yourself but if you don’t mind paying the money to install it then go right ahead. Great product for the price

I love magnaflow 447205,five stars for you thanks
