I've had mine on for around 1000 miles now. I can't say that I have heard ticking or noise of any kind from them. It might be that the Dinan Exhaust is drowning that out. Believe me the Bimmer is a lot quitter than my Vettes or my Tacomc with headers and Cat deletes. Maybe I'm just not as refined or worried about a little noise from adding performance items to the car.
