I've found that supersprint are currently offering the backbox linked below directly from their european base for £320 all in delivered.
Obviously thats near enough half price on what larkspeed (and all other UK suppliers) want for the same backbox so in that sense it's definitely worth it..
But what I mean is will I think half hour after fitting it: "why did I waste over £300 on this?!"
Other than slight increase in noise will it make a blind bit of difference?
Should I just pay £50 and get the chrome exhaust tips from BMW? (extortionate considering what they are but less than £320!! )
