Anyone ? Beuller ?

Check realoem?

So, my recommendation is to buy a used Genuine one. Even though this is not technically legal, new inexpensive aftermarket cats are garbage. The used OE one should last a while. I wouldn’t be surprised if the aftermarket pieces need to be changed for every emissions inspection.

I know nothing about this, where should he purchase it from ? I agree go oem but have no idea where to point my friend to?

realoem.com will provide parts number for all bmw parts, you start with the last 7 of his VIN.

Unfortunately, the answer is craigslist for part outs.. The original part is too expensive to buy new.

This.

Thank you to all for the advice, greatly appreciated!! I relayed the information to my friend and he was grateful.
