I HAVE A RACE BIKE WITH A HRC AIRBOX I HAVE HEARD ALOT ABOUT RUNNING THE SHORTER VELOCITY STACKS?
WHAT GAINS WILL THIS GIVE MY BIKE.??

I AM A TOOLMAKER BY TRADE SO I CAN MAKE MY OWN, CAN SOMEBODY GIVE ME SOME DIMENTIONS OR CAN I JUST CUT AND MODIFY MY ORIGINAL ONES AT THE MOMENT I HAVE TWO LONG ONES AND TWO SHORT ONES.

I'M SURE PEOPLE OUT THERE CAN HELP ME ON THIS ONE IF IT'S SIMPLE I CAN MAKE MORE CHEEP!!!!!!!!!!!!!!!!!!
