Has anybody heard anything about a "Valvetronic" type exhaust for the F56? I was under the car yesterday and given the humongous size of the stock can it would seem like a rather simple task to come up with one. I like the idea of toning down the exhaust on long drives but letting the engine "breath" when running the twisties. Being new to the Mini world I'm not familiar with a lot of the vendors from Gen 1 & 2. Any info would be appreciated.
