    M4 Slip-On Exhaust for FZ-09 14-17

    Harness the power of Yamaha's new three cylinder triple street fighter motorcycle -- the FZ-09! This M4 FZ09 Exhaust saves weight, adds power and gives your Yamaha an impressive, head turning exhaust note.

    M4 has released a carbon fiber slip-on exhaust system for Yamaha's new triple cylinder, the FZ-09. The M4 FZ-09 exhaust is a slip system that requires cutting of the stock exhaust during installation but the result, as you can see, is pure magic. In addition to the amazingly good looks and OE looking integration, the M4 exhaust for the FZ-09 will shed nearly 10lbs from your machine by eliminating the exhaust box. At present, the carbon fiber wrapped muffler is the only option but, in usual M4 fashion, look for other options to hit the market place. 

    The M4 FZ-09 Slip-on will add an additional 5 horsepower over stock.

      M4 FZ-09 can't go wrong
      by Vittorio G. on 07/27/16
      Pros: Great sound. Saves weight. Increase in power. \Easy to install. Just cut right next to weld.
      Cons: Nothing to mention.
      Great sounding exhaust on a budget
      by Justin H. on 10/07/14
      Pros: I'm honestly shocked how much I love this exhaust. It looks better than I expected, and is much lighter than stock. Sounds amazing. Plus, when you get bored, you can remove the baffle and watch your bike shoot flames out the back.

      The install instructions are clear. Make sure to have a grinder and dremel tools handy. It took me 2 full hours to cut, grind the pipe, and install this one.

      Take your time, it's not that hard.
      Cons: May need to remap the fuel after installing or risk of running lean....not sure though as I haven't done it yet.
      What. A. Difference!!!!
      by James A. on 06/23/14
      Pros: The difference in the sound between the FZ stock pipe and the M4 is night and day. I've had this on for 3 weeks now and every time I start my bike, I'm grinning ear to ear. The sweet grumble of the M4 at idle and while riding is unreal. When you back off the throttle there is a short period before the backfire kicks in. I think there are flames coming from the pipe during this backfire but am not positive. The backfire sounds awesome and happens every time you slow down. The look of the M4 is sick. The pipe is a neck breaka! Every where I go, folks are turning to see where that sweet sound is coming from. Surprisingly, it's not a Ferrari or a Lambo....Just my FZ with the best $400.00 I've ever spent. I'd pay double to get this if I had to. Slight gain in HP too. Icing on the cake
      Cons: It might be too loud for some.
