Nice deep throaty sound on start up, & just the right amount of rumble when you get on it, but not too much (didn't want it to sound like a muscle car, it's a daily driver). I was impressed at how it doesn't drone on the highway and I can still have a conversation with my girl as we drive. Definitly gave it some more umph and will turn heads when I get in it hard! Picked up about 1mpg, when I can drive it with stepping off in it deep(love the sound).
