I am running it this way on my 05, i like how it sounds, it's loud under acceleration but tollerable. It has a little drone under acceleration but i like it, but i'm also 22. While crusing i think it sounds fine. I was thinking about ripping the kitty off because i want it louder, but i think that will be way to load for me starting my truck up at 4:30 in the morning and my neighbors. Overall i would do it again on another truck.
