Bought it for a 2006 dual pipe crf250r. Very quiet bike for a 250. The fmf pipe came with detailed instructions as well as all the parts needed and a few stickers. Because it went on a relatively quiet bike the pipe didn't quiet it down a whole bunch but the tone is great. A bit more low end, great pipe if you want a good sound and a little power without making it super loud like a powercore.Read All Reviews
