I just installed a Weathertech hood deflector, and can not believe how much noise it creates at the top of the windshield. It sounds like hail is hitting the front of the roof pretty constantly anything much above 70 mph. It would seem it's redirecting the airflow so that the front w/shield side moldings are slapping around, but they're good and tight. Unfortunately I am going to need to remove and return it. Too bad, I wanted to keep stone chips off the front of the hood.
Who has installed a hood deflector on a NBS Silverado/Sierra that is not creating noise? Which brand is it?
i get a tough of noise sometimes with mine, all i have is the GM bug shield straight from the dealer. nothing fancy. the little bit of noise is worth keeping the rock chips down.
Thanks Alex. Maybe the GM shield is the way to go, I can live with a little noise, but not the racket the one I have is creating.

Well I bothered to read all the posts for this thread and I'll do the 3M tape application under the r/s and l/s windshield mouldings. Then keep an eye out for flapping hood hinge covers. Who'da thunk?
On my 2013 I installed the AVS hoodflector. I have no noticeable noise or wind turbulence against the windshield up to 78 mph and with the wipers going for a short distance.
