Customer Reviews

Standard Series Catalytic Converter, Federal Epa Standard, 46-State Legal (Cannot Ship To Or Be Installed In Vehicles Originally Purchased In Ca, Co, Ny Or Me)
I passed Smog
Once I got the old catalytic converter out the job was easy. The new converter slipped right in. I passed my California smog test with this as the only change on my 20 year old truck, where I had failed before. It cleaned up my hydrocarbons and NO.
