The oxa pipe gives such smooth power out put and keeps power and traction down, and a little cheaper then the leading brand fmf!!
Amazing!!

Never going back to FMF!
Got a OXA kit because it was available and dang I was impressed! High quality, sounded great and notable power gain for slower speed enduro/hard enduro riding. Seems to be holding up really well, have taken some hard hits to the header pipe and dents are minimal. My old FMF would be smoked by now.
