I have decided to sell my Eisenmann Sport that I took off my E60 M5. I removed the mufflers because I do a lot of long highway drives and after 10-12 hours at 90mph, the sound became a little too much. I have had many loud cars (Tubi'd Ferraris, Straight Pipe 993 Turbo) but never as a daily long haul driver. The exhaust sounds great, there are many videos around, and I loved the wail at high RPMs.
They were originally purchased from board member M5Converter. He had a relatively early delivery Silver Grey Car. The pics of the Silver Grey car are his car and the mufflers are on his car. The left muffler was adjusted after the pics were taken. As you can see in the pic of the left muffler on the black car, the tips were perfectly level. M5 converter had the mufflers on for around 3 months and 4-5k miles. I had them installed for around 3 months for another 3k miles.
I currently have the mufflers in NC but can ship them anywhere in the US.
Price: $1250 incl. shipping.
