Bank One and Bank Two are usually a standard layout. Look at the engine and stand with the belts and pulleys nearest to you. You will probably be standing in front of the vehicle looking towards the rear of the car. Bank One is the Left side of the engine. Bank Two is the Right side of the engine. Cylinder One will be the cylinder on the Left (Bank One), and nearest to you. Please use the attached image for reference. The front of the engine is also the front of the vehicle.

did you use oem catalytic converters????? the aftermarket converters break down very fast. thats why they are cheap. we have to replace them all the time due to bad catalytic converters.
SOURCE: How about when u have 2 catalytic converters in the same bank 1.?
If you have more than 60K miles start by replacing the Oxygen sensor(s) that is(are) installed after the catalytic converter(s).
P0421: Warm up catalyst efficiency below threshold. This code means that the computer is detecting the catalyst not warming up to full function quickly enough based on information from the post cat O2 sensor.
Good luck and hope this helps.

Bank 2 is the bank that is farther back than the other when looking at eng from the front you will see that one cyl head is farther forward (closer to radiator than the other. this is #1 Bank) #2 is the opposite and sensor #2 is the one after the Catyliac Convertor towards the muffler. #1 sensor is between head and Cat.
