Exhaust Header Insert Tork Valves

Exhaust header insert »Tork Valves«

Item №

These exhaust header inserts improve torque, throttle response and power. At low engine speeds, the taper of the Tork Valve increases back pressure resulting in increased low rpm power and torque. At high engine speeds, the venturi created by the Tork Valve increases exhaust gas velocity. This maximizes engine power by increasing the rate at which the exhaust gases are drawn from the exhaust ports. A horsepower increase of up to 2 hp over the entire rpm range were measured during Dyno runs. Tork Valves fit all OEM and most aftermarket pipes on both Evolution Big Twin and Sportster models.

These parts are not sufficiently homologated for the use within the purview of German road traffic laws. Therefore, use within Germany is only possible on the race-track, for show and exhibition purposes or for restoration of veteran vehicles. Which parts are legal for veteran-restoration, depends on the vehicle's age and must be seen about with the autorities in charge.

Outside of Germany, the homologation and a possible use in road traffic must be seen about with the local authorities in charge.
