328i M Sport exhaust debris -- normal?
I've had my 2103 328i M Sport for almost two months now and throughout this time, I notice quite a bit of exhaust dust/debris clinging to my rear bumper and exhaust tips. It always washes off without too much trouble but seems beyond what I would consider normal. My old E46 convertible had some exhaust dust too -- but no where near as much. The day after I wash the car, it is already obvious to me.
Perhaps this is because of the turbo? (first time I've owned a turbo)
Is this normal? Opinions?
