Magnaflow Catalytic Converter Survey 3.4L Only
Taking an informal survey. I would like to hear from all of you who have an Alero with a 3.4L V6 and have replaced the OEM catalytic converter with the Magnaflow Catalytic Converter Direct OE Replacement M6623520 and are still using both of the O2 sensors. Have you thrown any codes related to Cat performance or O2 Sensor performance after replacement? Also estimated mileage on new Cat and any relationship to thrown codes if any, your best SWAG? Please no bloviating and stick to the subject please.
