It sounds sweet when you get on it. I don't really notice a whine on idle either, but the long first shift gets the exhaust sounding amazing. As far as the 14.5 on instant, I drive down the highway at 59 miles an hour. After all I have a Hummer, honk I dare you. I had a Lincoln Navigator that did crappy on the mpg's too so it's not like it is any thing different than what I have been used too. Does anyone out there have nitto mud grapplers? Just wanting to know if they perform as good as they look! The truck came with Chip Foose 17 " rims, with BF GoodRich all terrain ko's, but I really like to mud, so I think that will be my next investment. Great forum, now my wife does not have to listen to me talk about my hummer! Win! Win!
