Great Product

This product fit my grandson's 2014 Honda CRF70 perfect. After I took off the stock pipe, it gave the bike at least 8mph. It sounds great too. I would suggest it for anyone to help their performance on their bike.

XR80R (2003)

System fit great, 10 minute installation time and sounds like a real 4 stroke. Seems like it is better on the bottom end but not a huge change. Looks and sounds great. If you are looking for major power increases, this may not be what you think. I would recommend based on looks and sound only.

2009 TTR-125LE

Pipe fit perfect but the rear frame attachment point was too small in diameter for the original bolt to go through. Went to the hardware store and bought a harder bolt/nut then the OEM and slightly longer to accommodate the new washers and lock washer I added. Lock washer keeps it from vibrating loose after a few removals. OEM heat shield remounted to the pipe perfectly also.

FMF POWER is right!

Great product and the fit and install was all good. Seem to really open up the XR and let it run. Great sound to boot. I would say the only downfall would be, you can NOT attach the heat shield. It does not allow for this. But a couple of hose clamps and you're in business. I would buy and recommend this product. Shipping was fast and here in no time.

GREAT

Put this on my 2012 crf100f with a k&n highflow. Sounds amazing, incredible torque. It greatly increased the high and low end speed and acceleration. Now it pops wheelies in 1st with a light touch of the throttle.

Great accelerator booster

I have a Baja 90 (Honda clone) and it already was great but I saw on TV. How pros had FMF's so I wanted one. I read online that if I ordered one for a crf70 than it would fit so I ordered it and it rocks!!! I can see how it helps me accelerate so much faster and it is the best thing ever!! :)
