hey, just wondering if anyone has installed a billet grill on their truck. i installed one a couple of weeks ago, and it makes a loud humming noise at about 60mph. im not sure if i just didnt do it right, or if all billet grills make this noise. any help on this matter would be greatly appreciated. thanks.

 

I did mine a few weeks ago, have a slight humming noise from the wind hitting it, not a loud one...
