I have a 2009 Dodge Ram 1500 4x4 with the 5.7 Hemi and 3.92 gears. Just finished a trip of 390 miles on 4 lane highway (keeping the speed to 70 mph), and 2 lane state highways (60 mph), and some through-town highways, and loaded. I had purchased the "Borla touring system" and was hoping for some improved performance and hopefully somewhat improved gas mileage. Performance is improved; sound is great. Mileage overall improved to 20.3 from 17.5 mpg at 45 degrees F. I am very pleased!
