Catalytic Converters
Cel P0422 Main catalyst below threshold(Bank 1). I believe it's the drivers side cat that needs replacing. Dealer wants 1600 for one side..anyone know any better routes to go? Maybe high flows instead and where to get them? Any input is appreciated..TIA.

300E a couple 1994 w124wagon E320 Wagon/,1971MGB Track/Rally, MG Midget Autocross ,2000 E320 wagon.
They need
to flow the same or your cylinder balance will be off,also how many miles on the car?usually there is a reason cats fail,you need to check,compression,oil burning and o2 sensors.
ohlord
also eastern cat has oem universal cats for about 50 each for the e320 don't known how much for the amg,give them a call.
a good tutorial link below.Read it

Now you point out that you have non oem cats,have you cleared the code and inspected the cat in question,if non oem you may have a lazy o2 sensor.Clear the codes,harbor freight tools has an obd2 scanner #94169 for 39 bucks.works great.listen to the cat is it rattling or if you hit it with a rubber mallet do you hear stuff bouncing around?
then at the price of a cat I would spend a few bucks and go to an indie shop that has a scope and check pre cat and post cat o2 sensor values,it will show you if it is the cat or a lazy sensor.Run from the dealer,any good indie can do it.

It is the cats, it makes a tingy/rattle noise also. I want to go a different route than the dealer because of the price, but they did check my car for free there.
