FMF Power Core 4 Slip-On Exhaust

The exhausts of the factory bikes have the bling factor but the PowerCore 4 Slip-On has similar power, more durability and a much lower price tag. In addition, the stainless steel and aluminum construction will cut weight compared to the stock muffler. For the real world dirt biker, this is a very good option for bumping up the power.
  • Race inspired price point muffler made for maximum power output Aircraft quality extruded aluminum canister with stainless steel components
  • Space Age internal packing for maximum packing life
  • Hi-Flo modular end cap
  • Internal shape of core uses Hi-Flo technology
  • Enhanced sonic evacuation provides for higher flow and increased power
  • Spark arrestor included

FMF Power Core 4 Slip on Exhaust

I bought this pipe for my 2007 WR250F. It’s not only improved the power of the bike but it also gave it a really nice sound! It is considerably lighter than the original exhaust and has a really nice look to it too! If you’re looking for a quick upgrade this is it. It’s very easy to install and is priced very reasonable.

I installed this silencer on my 2008 Yamaha WR 250R, & It made a huge improvement in power & sound! With the stock muffler, it took a lot of effort to wheelie the bike, but now I can easily wheelie 2nd through 4th.

This pipe is the best thing you can do to your bike. I put this thing on my 2003 xr100r and it sounds like a 250 and much more torque and power.

Power Core 4

I love this exhaust. It bolted right on with no problem and gave my CRF230F more kick. I would highly recommend this to anybody thinking about up grading their exhaust. Not to mention the price since the closest any dealership close to me could only get as close as $50.00 more than what I was charged here. Great deal.

I LOVE THIS PIPE AND REALY RECCOMEND THIS TOO EVERYONE WHO IS LOOKING FOR MORE TORQUE! I was having trouble getting wheelies out of 2nd gear but now I can wheelie 2nd through 4th!

Good sound investment

This slip-on along with a PowerBomb header and jet kit. The setup changed my CRF450X power band so much its from night to day. The look and sound is way better than stock. You can't beat the price and sipping was fast 3 days.

awsome set-up

i put the power core 4 q on wr250r last fall and the improvements in throttle response on this small bike are really remarkable now all i need to do is get my fmf programmer on that my wife got me for Christmas, if it adds as much as power as the pipe, maybe i won't have to be waiting for a fuel injected wr450r if yamaha are going to come out with one in future

Well Worth the Investment

Kudo's to FMF for making a product that is so easy to install and offers such immediate performance. I put this on my '08 wrr and the increased power is great. The sound is a lot better than stock as well. I will certainly buy FMF products again. Motorcycle Superstore's customer service rocked too.
