I will be replacing the catalytic converters on a 2007 Honda Ridgeline. This is the J series engine so the repair would be very similar for the Pilot, Odyssey and V6 Accord or Acura TL.

The DTC codes are P0420, Catalyst System Efficiency Below Threshold Bank 1, and P0430 Catalyst System Efficiency Below Threshold Bank 2. Bank 1 on the J Series is the rear catalytic converter and Bank 2 would be the front one.

There are many ways to "skin the cat" and these are the methods that I use. Any criticisms or alternate methods posted in the comments are welcome, just keep it civil.
