M550i exhaust upgrade, which one?
So it appears that Dinan, Acropovic, AC-Schnitzer, Eisenmann, and Remus all have an exhaust upgrade for the M550i so which one do I choose?
Goal is not necessarily for performance, I'm looking for a much better sound than stock. Would like it louder and deeper. Would prefer to do just axle back but if I have to go cat back I would possibly do it.
Thanks for your input...
