i know iv read about this before but have had no luck in finding it again... i got the top of my airbox off, now what do i need to do to gain a extra 5hp?i believe cut out all of the things inside to make it smooth? also has anybody tried the crankcase breather mod? if so, do you have a picture of which hoses to connect?

 

i think what you have to do is rip out all the emissions stuff, i dont ever remeber seeing it on here but over on the other forum who can not be named i saw it once a while ago
