About this 3D model

This is a Dyno Tested Velocity Stack set that was tested and gained extra 5hp with the proper tuning on my Semog Bravo Sport Crosskart with a GSXR L6 750 engine. This Engine mid range is extremely powerful but with a drop at high rpm, so we used this type of stacks to gain some more HP at high rpm and improve traction mid pull.
