2005 FLHRI 95" S&S 510 gear drives, bigger valves ported, radius valve job. I just got my D&D Fat Cats installed and dyno tuned. These look and sound great, lack of installation instructions cause a lot of trial and error fitment to get right. I had stock head pipes with V&H ovals installed. After tuning I ended up with 4 hp increase. Bought fron Shawn at DR Vtwin, great service and great price couldn't ask for better customer service. Highly recomend this sponsor.
 
I bought from Dr. V Twin as well , they are easy to deal with, I gained 10hp on a built motor but only 3 lbs. of torque, however the torque hits at lower rpm's than before
