Just got a 2007 mustang gt it’s straight piped and I need to pass emissions here in texas. Ran obd2 scanner and it read a p0420: catalyst system efficiency below threshold bank 1 and p0430: catalyst system efficiency below threshold bank 2. Will installing a catalytic converter clear these codes? I was looking at a SLP Performance high flow catalytic converter M31040. I did noticed this cat doesn’t have the sensors like the oem cat does. Does that matter for emissions? I just need to clear...

Need help! Catalytic Converter
