I like the 90mm Sport. It sounds really very good. Little louder would be good when driving alone, but on the other hand it would be out of character with the car, unless you could turn it off. The Sport sounds great and people like the way the car sounds.
I think 90mm Eisenmann Sport is the ideal choice for this car. This should have been the OEM exhaust. It is everything I expect of an M5.
Do you have any experience with Race and Akra in terms of sound and loudness? I have no experience with any of these, and kind of have to base my purchase from the forum. The only experience I have is Akra on my E92 M3. Would be really awesome if you can talk about the Sport, Race, and Akra if you have experience with them.
