Worth every penny!

Comments On Sep 09, 2014:You just can't go wrong with FMF. This system made a HUGE improvement over stock on my 2014 yz450f. It added horsepower and smoothed out the power band while also saving a boat load of weight. Extremely well made and easy to install. FMF even provides a how-to install video on YouTube. It has to be the easiest modification you can make that produces the greatest improvements. Highly Recommended!
