i just bought the new fmf pipe at my local ktm dealer and the sound is just
amazing.Not quite as loud as akro without the insert but much louder than stock.i compare that sound to a ducati its very deep and very mean.
i rode a 950 with the akros they are cool,loud and very expensive also very lightweight since there made out of titanium. the fmf are lightweight also i compare the weight of the stock and the fmf and its almost unreal.the ktm advertising says that you will shave 10,9 lbs and its true.have fun both models are cool almost same sound and 350$ cheaper
Beat the crap out of it!
