I don't have a Dyna so I don't know if it provides more ponies or not. I can say my gas mileage went DOWN 1 mpg. It is a lot louder not especially in the cab of the pickup you can hear the engine growl now, not sure if I like this. As for install it was super easy I put it on in about 30 minutes very simple and the instructions were pretty good.
