- Change your bike's power characteristics to match track conditions and your riding preferences using interchangeable velocity stacks
- Depending on the velocity stack you use, you'll get better bottom- and mid-range power (longer stack) or mid- to top-range power (shorter stack)
- Improves throttle response regardless of stack selection
- Velocity stack works as a resonating pipe thus the length of the pipe changes the dynamic tuning range by adjusting the pressure pulse frequency
- Includes AIR4ORCE tunable intake system, two velocity stacks and detailed instructions; hose clamps and gaskets are included for models that require them
