Picked up a 2013 FLHX. Looking to upgrade the cam chest, breather and exhaust. Nothing radical but looking to add a little more horse and torque. The exhaust I am pitching around either RC Power Max or VH Power duals and High Output mufflers. Really undecided on the cams. I am figuring on a new plate, oil pump, lifters and bearings as well when I get into it.
