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!Read All Reviews

Bought this exhaust because the stock pipe was too loud with the baffle removed. It is within a half pound of the stock pipe weight (was expecting it to be lighter). It was easy to install and looks good. It is mounted solidly and I have several rides on it now and have not had any issues. It is now quieter than the stock pipe with the baffle removed. This pipe is a good value.Read All Reviews
