carb legal catalytic converters for 2006 IS350
Does anyone know where I can purchase C.A.R.B. legal catalytic converters for a 2006 IS 350. I am having a hard time finding them. Apparently I need both sides because I keep getting p0420 and p0430. I've replaced the 02 sensors in the past 3 months and the codes still come up. I even went to the local Lexus dealer and was told that one side was available at over $1100, but they had no idea when the other would be. Any information would be very helpful. I have time because it doesn't have to be slogged till next March.

Most common cause of P0420 and P0430 on our cars is an exhaust leak under the heat shield by the Y-pipe. I would definitely check for that issue before replacing your cats.

Agreed. Be aware that most Lexus dealers also replace this very expensive component which includes the pipes and cats (at around $2,000 in parts and labor) in the event of the very common exhaust leak I mentioned earlier. An exhaust shop with a welder can repair the corrosion damage for a fraction of that cost.
