Straightline’s single pipes produce a wider power band, with great bottom end power, and improved top end speed.  The Straightline Polaris 850 single pipe powerband is changed to create a torque monster.  Power from 7700-8050 with no loss and improved torque!   The midrange gaines are the most impressive in the industry with great response, hole shots, and that mid range pull that wont quit.  Be sure to check out the dyno sheet overlay to see the power.  Clutching is extremly important with the Straightline single pipe.  When changes mid range power, and peak power this much a change in clutching is required.
