Eisenmann offers two performance levels and two tip styles for the E63 M6. The Race performance with the Oval tips has been the most popular. The Race when combined with the V10 sounds very exotic.
The Sport performance is just a little louder than the OEM exhaust. The Sport performance sounds be when combined with a Supersprint X-pipe. We have the Race Oval in stock for the M6. Pm me if you need any help
