hey I have a 84 300CD. I am pretty sure it is a Cali version. I have that extra part in front of the turbo tho. I think it is a KKK turbo also, since this was missing in my old 83 300CD which I believe has the Garret turbo. Do you guys think I have the trap oxidizer and if yes I would like to order this bypass kit!

P.S. I know the trap oxidizer versions have a smaller air filter assembly in a different spot towards the front of the engine. I have the normal set up where the air filter assembly is bigger and on top of turbo.
