Was wondering how loud the legal exhaust's are? are they louder or just deeper that u tihnk that they are louder?
Have RPI (not legal) and i know the db are up to 115db at maximum.
How loud is Eisenmann sport or Supersprint sport?
Are the race versions a lot louder? comparable to RPI?
I wanna know everything about every single exhaust for Z4m
And what means S.U.S and T.I. on exhausts?
