Has anyone been asphyxiated staring into the exhaust pipe? I guess that if they were they wouldn't be posting about it.
But seriously, it sounds like there is little sound gain with the second pipe permanently open. You would think that there would be a minuscule mpg improvement with the mod, so BMW (who would kill to improve their car's MPG) would not spend money installing a device that would do the opposite. Am I missing something here?

Re: MPG Golf T has zero impact on mpg. You need better flowing exhaust at higher RPMs. At higher RPMs valve opens anyway. They install the valve for refinement and better NVH. A normal consumer doesn't want a car to be loud unless pushed hard.
