The fmf power core II is $94.00 and the fmf fatty gold series pipe is $181.00 it will be $265.00 if you buy them together. I would get trinity pipes and silencer if i were you the fmf dont add any horse power it stays the same the trinity pipes change the blaster from 17.9 to 20.3 i hope this helps.

 

I just put the Gold series pipe with the Power Core II on my brother's Blaster, along with reeds and rejetting. Amazing increase! That thing really runs. Also put 18" wheels on the rear. Lost a lot of top end, but it's a monster off the line.
