product description

Torque Valve Torque insert to increase torque in the lower speed range.
This exhaust torque insert works similarly to a valve, which
prevents backflow and thus fresh gas contamination
counteracts.
This means that exhaust gases cannot flow back into the combustion chamber. The result is better cylinder filling
(especially at low
speeds) and therefore higher torque. The very special shape also ensures
the Venturi effect.
