- The industry's first changeable internal stinger for Polaris allows for adjustments for high/low altitude or race application adjustments. Smaller stinger size will increase the pipe pressure and compensate for low pressure at high elevation. In race applications a smaller stinger will cause pipe to react much quicker and require less preheating of the pipe on a rev stand.
