    Comments about FMF PowerCore 4 Slip-On:

    Great little pipe. Much lighter than the stamped steel factory unit, easy to bolt on, and inexpensive. gave my little 140L some much needed top end kick when jetted and uncorked correctly. sounds mean when you open up the throttle, but quiet enough to not disturb hikers when you lug it on the trails. very durable; has been crashed on many times, and not a single dent or scratch has appeared. easy to repack but it is a bit fat.

      Got this for my 2007 YZ250f. This exhaust is vary easy to install! Sounds great more power! The stock muffler on my YZ did not have a spark arrestor! The power core 4 does! I ride trails so that's a A+ for me!

      Comments about FMF PowerCore 4 Slip-On:

      Fits great and it rumbles nicely at speed. And with a little finess it can be nice and quiet when coming home at two in the morning. It could use some heat shields tho I've got a few burns on the cuff of my riding jeans from it now.

      Comments about FMF PowerCore 4 Slip-On:

      Compare to the stock exhaust i had on my crf 230m it sounds 100x better, very loud,feel a difference in more torque it gives you a little more juice, and very easy to install
      only con is I have to be careful on reving my bike near a cop because they could stop me cause the loudness and didn't bring a clam to seal muffler to the front but you can buy one at the store but other than that I recommend it if you wanna upgrade from a stock exhaust
