Will Magnaflow produce an exhaust that has the same appearance as the Brooklands system? If not you may as well go with one of the more tried and tested systems such as G56, MMC or Krazy Horse. A shame if you go that way as the exhaust is the main distinguishing point, after that it becomes a green M3W with badges rather than a rumbling Brooklands. I believe the MMC "final Brooklands upgrade" is no longer an option, your choice may be limited.
