heath freelandville,  IN 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

KC corona,  CA 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.

James Bernard san diego,  CA gnar 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.

Jason Childress Oklahoma City,  OK 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.
