Pro-Circuit / FMF, V-Force / Boyseen

I purchased a 2001 Yamaha YZ 125 for my 14 year old son to race. We would like to make some modification to it and I was wondering which of these products would perform better in this bike and what would be gained if anything. The Boyseen Rad Reed or the V-Force Reed Assembly. The Pro-Circuit Plattium Pipe or the FMF SST Pipe? Anyone have the answers?

i have a pro-circuit works on my 2000 yz125 and a factory sound 304 silencer and it works awsome, i have stock reeds in it. personally i like the pro-circuit exhaust better than the FMF, boyesen and v-force make good reed assembly's if i were you id get the v-force reed assembly and the pro-circuit exhaust

Get the Vforce, period. No comparison. The SST pipe is good but the Pro Circuit pipe and R304 Shorty will add loads of bottom, good mid, and plenty of top!
