Summit Racing™ exhaust insert cones are used to reflect and dissipate sound energy, effectively reducing the decibel level. These are manufactured from T-304 stainless steel and due to the open nature of the cone, it does not significantly increase back pressure. The inserts are sold in several different size to suit your individual needs.

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.
