Catco No Returns Accepted -Catalytic Converter
$159.99
Q:Will this work with a 5.0 mustang?
Jose R.
A:BEST ANSWERHi Jose, I am pleased to assist you. This universal catalytic converter can technically be used with a 5.0 Mustang. However, careful consideration of compatibility and installation requirements is necessary for optimal performance. The converter is EPA and CARB approved, which is beneficial for compliance. Installation will require custom modifications, including cutting and welding of the exhaust system to fit properly on a 5.0 Mustang.

P0430 Code: Catalyst System Efficiency Below Threshold (Bank 2)
P0430 Code: Catalyst System Efficiency Below Threshold (Bank 2)In most cases, a vehicle with an inefficient catalytic converter will continue to run just fine. But if the converter is obstructed internally, it can cause poor engine performance and may even damage the engine in the long run.
P0042 Code: HO2S Heater Control Circuit Bank 1 Sensor 3
P0042 Code: HO2S Heater Control Circuit Bank 1 Sensor 3Bank 1 is the side of the engine where the #1 cylinder is located. P0042 code is set when your car’s PCM determines a potential problem with the heater element circuit of the oxygen sensor.

How to Tell If the Catalytic Converter is Clogged
How to Tell If the Catalytic Converter is CloggedA clogged catalytic converter will present symptoms, while a chemically failed cat con that’s not clogged typically just illuminates the check engine light or malfunction indicator lamp (MIL). Also, if the cat con that just fails chemically but doesn’t clog is not the light-off cat con (the cat con closest
