That has to be some kind of air box and yeah imagine the whiny noises from turbo(s). Yikes!If thats interior snorkels, thats gotta be loud AF right by your ears. I wouldn't have guessed dually until you showed the photos of the rear duals. I was just going to say big tire slicks, but hankook dynapros aren't slicks. I definitely have more questions look at all the photos, but man that is cool!
