Hey there group. I was wondering if anyone has any advice on catalytic
converters. I've searched near and far for detailed information on
replacement parts and there is absolutely nothing. As far as I can
tell I have three choices the BMW replacement part ($1100 ouch), the
Miller part ($746 ouch), and the DEC part ($346, I can deal with that).
I want to know if anyone has any knowledge of these parts or any
experience replacing this unit. I'd hate to dump a ton of money into
the car and find out the part I bought was total shit.
If anyone can lend any information it would be of great value to me.
Also if anyone has any tips of replacing this unit I.E. other parts I
should buy/replace at the same time, tips, tricks, pitfalls etc.
