    Any ideas on how to replace or any mods other than buying the whole exhaust manifold. I haven't seen any reduction in performance or fuel economy. I avg around 16 in the city and 19-20 on the hwy.

    BTW I have a '06 Double Cab 4X4 6spd Manual.

    Sure it's the cat and not the downstream o2 sensor?

    Some have had luck with 'washing' the contaminants from the cats with oxalic/citric acids. Others say to heck with it and put on DTLT headers.

    Yeah, I took it to Toyota and had them check the code and said it was the cat on the left bank.
