Like brand new, over $7,500 from BMW. It's off a 2014 M5 ('competition exhaust') . Was on his car for 2 weeks before owner put a new after market exhaust on his M5. I just bought this off a member on here, for $1,600 shipped 2 weeks ago. I was going to put it on my car, and lower my car but decided not to because I'm going to get a M5 in a few months. So why bother.
Let me know if you are interested.
