Well Guys, I'm really surprised how great the sound is!
The Z4 sounds really great, although I have the German "TÜV" version.
This one is by far not that loud as the US Version (Race in Germany)
Anyhow, lots of my friends (driving BMW M's with sport exhaust) like the sound very much.
Anyhow, Eisenmann needs my Z4 once again next week for about 2 weeks.
I personally will relax during the fine tuning time in the Dominican Republic
and hope to pickup a great sounding Z4 by mid October
(when it's getting really ugly in good old Germany
)
On Saturday I'll take a sound file (I'm on a dyno with the Z4)
Guys.. it's worth waiting.. the sound is "pornography"
Take care
Tom
