SMOG Help! Need "E.O. CARB" number for Magnaflow Cat!

Hey guys,

Tried to get smogged today and the two shops I went to did a full visual underneath the car.

My intake has a CARB sticker with the "D-XX-X" number stamped on it, but they couldn't see anything stamped on my 42DD turboback.

My exhaust is 42DD and their website says they use a Magnaflow CA cat.

What is the E.O. number I need to use?

D-193-89 - lightly engraved on body - assuming you ordered this option as oppossed to their regular hi-flo cat.


Keep in mind the number is NOT for your car. CARB numbers reference a series of cars that have been approved to use them. If they just see or know the number that is usally enough but technically if they go to the book and reference the number it is not approved for use on our cars. I always just put my stock downpipe.

if its not oem don't take it. what GIACUser said, stock downpipe

It's why you keep stock dp in case
