I forgot how old i'm getting and got magnaflows installed on my Z4M Coupe 2 days ago. I'm willing to part with it for $600 if someone is interested (plus cost of removal at a shop). It has flanges on them so you can swap out with your stock by just unbolting it. The tips are 3mms larger than the stock but has the same setup where the inside pipes are out slightly more than the outer ones. I'll post pics up later today. The cans are painted black and tips are shiney stainless steel. We can swap out tomorrow if you can find a muffler shop that's open. I'm in West LA.
Cheers,
Mike
