The installation was not that difficult although I did have to drill a hole for my temp sensor which I was not expecting so it took longer than expected. My truck actually runs quieter/cleaner at idle and when I accelerate. I do get a nice purr when I hit the gas but it's not a load overpowering sound anymore. So far so good. Too early to tell regarding gas mileage.
