Just went to get my titan inspected and it failed because of the p0430 and p0420 codes, which are the catalyst system efficiency below threshold banks 1 and 2. Apparently I have to replace my catalytic converters, called Nissan and they want $2100 to fix replace them. I know nothing about trucks and how to replace these.
Guess my questions would be how much should those cost, and how easy are they to replace?

thanks for the help

That sounds about right. Are you still under the 8 year & 80,000 mile federal emmissions warranty?

No, have over 115000 miles on it. Was hoping id be able to do it myself, how much should the front 2 converters cost by themselves?

You can do it yourself. Just be patient because they are not easy & hope you dont break off an exhaust bolt in the head.
