If you've got some, please let me know and give me a price. I've got a P0420 and nissan is giving me hell about having history on my truck's title so they won't work on it.

Any help is really appreciated. Thanks

Tried changing the after-cat o2 sensor on the driver side, no fix, must be a bad cat.

Steve500: I've got a set of primary cats with about 19k miles on them. I would let them go for $325 shipped.
