Comments about FMF - Factory 4.1 RCT Slip-On (Husqvarna):

FMF produce a top quality slip on, super light and strong but the increases in performance are astounding. Really opened up my FE350 over stock and gave it a great sounding note as well. Throttle response and bottom end power is up, love it. It looks factory as well.
