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.
