HardDrive exhaust torque valves, or torque cones as some like to call them, are designed to give back some of the bottom end torque that is lost when drag pipes or exhaust systems without baffles are used. HardDrive exhaust torque valves fit a variety of applications and are made from durable stainless steel.

Kuryakyn torque cones are designed to create a back-pressure while accelerating the exhaust gases through the pipe to avoid resonance. Long rides are more pleasant with the cones installed because the engine has a more constant response. Smooth out your power curve to provide a more consistent performance—and recover some of that lost horsepower and gas mileage without affecting the sound. Torque cones are available for a variety of Harley-Davidson® bikes from 1984 and up.
