I'm copying this thread from my posting on M3forum but will discount for Z4M owners;
I took these off my Z4M to return to stock. I bought them used from another Z4M owner so they've been successfully mounted to at least 2 S54s. They have some scratches where they were rubbing on a suspension mount, a somewhat common problem with e86 fitment. The rear O2 sensor you see will be included since I can't get it out, shouldn't be a problem if you have a bench vise to hold the header while you wrench (I don't and I don't feel like dealing with it). That sensor was throwing a code so I would assume it is dead and replace with your working sensor.
I'm basing my asking price on the following thread since it was the most recent JVT sale I could find, selling for $350 in about an hour;

Given the above mentioned items I'm asking $300, as-is, just as you see pictured and with everything that you see pictured. I take paypal only and first to pay is the only 'dibs' I recognize.
Thanks
