BMW M2 Prototype Spied with Quad Exhaust

The 2016 M2 (F87) is spotted testing and shows quad exhaust for the first time. Quad exhaust is a hallmark of BMW M vehicles and its nice to see it on the M2 with wheels from the M3/M4 prototype which did not make production. Earlier prototypes were testing with the M3/M4 19″ Style 437M wheels.
