I am looking for a nice sounding M3 E9x exhaust and was looking for some more options.
I suppose Eisenmann has got a race and sport version? one with and the other without TUV?
The M5 e60 eisenmann race version is the loudest exhaust out there with and is the best if you are looking for the loudest, but is has a drone in the cabin, does the race exhaust M3 version drone too?
I am in Europe and eisenmann seems like the best way to go, any complaints?
