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.

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
