Magnaflow 23405

Would you like to buy Magnaflow 23405 Direct Fit Catalytic Converter (Non CARB compliant) DisappointingBy OldProI bought this to replace the plugged OEM cat on my 2003 Monte Carlo. After installing it and starting the car, I discovered that there was a 1" gap in the weld on the inlet. I contacted Amazon and got a replacement shipped right away (thank you Amazon!) but the car was laid up until I received the new one. Installed the new one and it worked well for about a month, then the car starting throwing P0430 errors (catalyst efficiency below threshold). I needed to buy a new cat and go through the entire removal/installation again. A HUGE waste of time and money!2 of 2 people found the following review helpful. » More Information about Magnaflow 23405 Direct Fit Catalytic Converter (Non CARB compliant).
