Has anyone considered long term maintenance issues with the internal bimodal flaps in the exhaust tail pipes. The internal flaps look shiny when the new vehicle rolls out of the dealership, though they do become covered in carbon soot quickly. Has anyone experienced issues with sticking or dislodged valve flaps? The actuators are made in Germany and seem to be high quality units. The stainless steel tail pipes are made in China (sad but true). I keep my tail pipe surfaces in showroom condition though I have not cleaned the internal exhaust flaps....does anyone reccomend throttle body cleaner spray and a gentle wipe of the flap (hard to reach anyway).
