These stacks were designed with racing in mind for the 2017+ GSXR1000/R. We aimed to push the power as far and high in the rpm as we could because that's where the GSXR needs it. These can be directly dropped in for more power and tuned to get the best! We were able to see peak gains from 5-7whp and at 14k RPMs over 10whp
