First let me say it got to 67 today and I got to ride. A month ago I had my FXDF FatBob at the Dealer installing a SE a/c, KromeWorks 3" slip-ons, PowerCommander and I had it Dyno'd. Oh, my God. Not only does it now sound like a Harley, it goes like a Harley. The Dyno shows an increase of 10hp and 10 on the Torque. So, like I said, I finally got to take her out and see what the heck I paid for. It would seem that I would wind it out in 3rd at 30mph. Now, I hit 45 to 50 in 3rd and it just wants more troddle. The FatBob is a beautiful bike. But stock, no power and no sound. The total bundle cost me 1050. That included pick up and delivery. I'm glad I had it Dyno'd so I can see what increases were made. But that's on paper. In the saddle I can feel the increase. I'm also hoping it decreasing the temperature a little. Couldn't really tell on first ride. To dang exicted on the sound and power to notice any heat change. Plus at 67 degrees, it was perfect weather to let her breathe. I know each his own when it comes to sound and pipes. But if you have a stock FatBob, and want it to run, I recommend a Stage one. The 3" Krome Works slip-ons ran 279. Same looking as stock pipes but now it sounds like it runs, GREAT. Thanks for letting me brag a little.
