My nephew is 12 and doesn't race. I already baught him the FMF fatty with a turbine core silencer s/a. But in in these web site threads someone said FMF stinks, Hetrick,LRD,trinity and Paul Turner Blow FMF away. If anybody can give me some imput, again he is 12 and doesn't race and tthe only other mod will be K&N filter with air box vents (lid ON) Thanks

Pro Circuit all the way, they kick ***, my friend has fmf on his blaster and my blaster kills his.
