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

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.

AWESOME
I put this pipe on my 1994 KLX250R and there was a huge improvement in the torque, power, and sound....It wasn’t too loud and was a awesome deal for the money! 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!

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.

Great Pipe on the Cheap
Needed a cheap pipe, bought the cheapest one they had. Fits great, sounds fine, made some power...who could ask for more?

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.

Great slip on great price
This pipe seems to fit what I needed exactly. I ride dual sport and it’s not too loud for the street and really seems to have opened up the breathing. I can really feel the added punch and would recommend this slip on for the money!

FMF Power Core 4
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.

Great Pipe for 07 WR250F
Great sounding pipe, but I may get the quiet insert, as it is a little loud for the dual sport rides I do. Overall it's a good buy, but you will have to re-jet, my bike required main and pilot change, oh and added fuel screw to dial it in perfect.

FMF - Power Core 4 Slip-On Exhaust
Makes my YZ250F run like a 450 on the bottom and mid-range. FMF needs to either design the slip-on to accept the stock rubber mounting washers or include a rubber gromlet/sleeve to prevent vibration from fatiguing/cracking the mounting tab on their slip-on.

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.
