    FMF Factory-4.1 RCT Stainless Steel Silencer

    jeromy in NE

    instant performance upgrade

    Besides the coolest exhaust note yet: this along with the FMF Grunt added imediate & noticable improvement in the throttle response & low end for my bike over the stock silencer. I hope I don't have to but I'd purchace it again. I typed FMF grunt when meaning FMF Snap.

  • FMF Power Core 4 Hex Replacement Spark Arrestor Screen

    FMF Power Core 4 Hex Replacement Spark Arrestor Screen

    Roger in IN

    Good replacement

    I put a little too much permanent flex on the muffler at the header pipe and the screen caught the excess at start up. It torn a hole in it so I had to replace it if I want to trail ride on DNR land

    FMF Power Core IV S/A Silencer

    Roger in IN

    Great muffler

    This muffler looks awesome, sounds excellent. Sound at idle is just a little bit louder than stock. When you get on it it is about 20-30% louder than stock. It sounds great. Good improvement gain. I installed this muffler, the fmf power bomb, and the fmf power management in about 45 minutes. Huge difference. Great power gains

  • FMF Wash Plug

    FMF Wash Plug

    Chris in CO

    Don't leave it in while traveling

    My mistake probably, but one day on the way to the trail, there was heavy rain so I thought it would be a good idea to put my wash plug in the 'ol exhaust. The flag that says "remove before flight" now says "Remo" because the flag ripped in the wind. Bought it cause it looked cool, although it still works great it doesn't look cool and that is why the 2 stars, cause the cool money could of bought me a sticker that at least would be stuck somewhere.
