Check engine code P0420 & P0430 (Catless)
Recently Bought CLS550 2012 and found out that the cat's have been removed and the cat's have been removed and check engine codes are P0420 & P0430.
So I'm thinking of installing a non-fouler same as the attached link or a 90-degree fouler or .......
Has anyone done this or have another solution for this CEL.

I've read that the 90-degree ones work. Where did you buy the car? If it was in the US, you could make the seller replace the cats, they broke our emission laws. Marv

As I already bought I dont want to go back to the seller and that long process, and in my country, the car won't enter an emission test only after a car completes 10 years of manufacture date so still 2 more years.
Plus the car drives fine and the mileage isn't affected.
Will try the 90-degree fouler and will update you.
