Catalytic Converter

[macsgsxr]

I have a 2007 chevy silverado 1500 5.3 motor two wheel drive. The driver side Catalytic Converter starter riddling pretty and now miss firing codes on computer. I found out its a dealer only part in california. Just trying to get information on a unversal cat for this truck. Not really worried about the o2 sensors.Thank you for any help.

Take it back to the dealer as it has a factory warrantie to 8 years or 80,000 miles
