Do NOT break out the brick and sell it that way. It has been discussed ad nauseam here. You will get FAR more out of the converter by the end buyer knowing what it is in its shell. If you put brick in a drum they will have to test and sample it.. you could have good ratio brick mixed with aftermarket brick.
My suggestion is find an automotive
CORE BUYER. $150 you are getting is decent.. but depending on the model of BMW etc.. you could be losing a good bunch of change by selling each one at the $150.. you may come out even- some may be $90.. another may be $200.. you'd be at $155 so $150 isn't bad.. but if you have a core buyer- you get exactly what you should get for each cat.
