i'm going to be purchasing a exhaust for mine in the next few weeks. i was initially going to get a supersprint race. but after looking at the eisenmann boxes i perfer the tail pipe design slightly more and it seems to retain the m3's rasp a bit better.
tail pipes
has any one on here had experience with the eisenmann exhaust? if so any drone from them and what kind of db's do they tend to read?
