Great performance per dollar upgrade.
I have heard Graves develops its products on the racetrack and these Velocity Stacks for the FZ1 back that claim up.
No other stack that I've researched has the staggered height of these.
The bump in power across the rev range is demonstrated by dyno testing and is especially worthwhile if your FZ1 has been ECU-flashed and had airbox opened-up.
Now I'll have to save up for the full Graves exhaust system for even more power :)
