  • FMF Power Core 4 Hex S/A Silencer

    FMF Power Core 4 Hex S/A Silencer

    Sam in CO

    Great pipe for a great price

    If you've mangled your pipe in a crash, look no further. This is a great pipe at a great price. I can't say one way or another about any power increase as I've never ridden my bike with an OEM pipe, but I wouldn't hesitate to buy FMF again. Only complaint is that the "graphics" on the pipe scratch very easily and the graphics on one side peeled completely off.

    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

    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

    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
