"i put this exhaust on my 2010 honda 250f. the bike was kinda slow stock but ive never noticed such a power gain from just an exhaust as much as i did with this one. it also sounds great. it sounded like the bike had motor work from just the exhaust. i have a full race motor in it now and this is the best exhaust ive ever ran on any of my bikes! GET ONE!!!!!"
