I've seen (or heard) an R56S with a BOV fitted back at MINI United in 2007, can't say who it was or who fitted it I'm afraid, but have seen it done.
I'm not a fan I have to say, I'd rather leave the pssssst noise to the jap boys with their sccobys and evos
It just doesn't befit the MINI in my opinion.
But each to their own
