El Diablo on Fatboy 114.
By Thom K. on Verified Purchaser
The chrome and fit are perfect! My Fatboy is a 114 with a S&S 475 cam. Db at idle is 84-85. Runs really stronger than the Shark Road slip-ons which I did have and were really loud. At idle with the cam was 90-91 Db and the cruise was almost unbearable. Using Powervision tuner with Fuel Moto tune they provided. Now runs and sounds like a Harley. The next step will be the S&S 128 kit.
