My Catalytic Converter was stolen off of my 2007 Toyota Prius. The shop replacing it does not like Napa replacement parts, but my insurance will not pay if he uses a better part. My questions are: 1. are Napa parts for the cat good still? and 2. Do the parts carry sufficient permanent, non-removable identification so as to identify the manufacturer. Such identification shall be accessible to the greatest extent possible after installation? Thank you, Sharon
