(Please note that this is a replacement unit in case your CAPRISTO remote becomes defective). The reason to have exhaust back pressure control is to obtain a better engine torque band and to maintain drive-ability in a wide range of conditions. Today high performance engines prefer a free flowing exhaust at wide throttle openings and high rpm. At smaller throttle openings and low rpm encountered in traffic, a slight increase in exhaust back pressure, results in better low end torque and a more user friendly engine. This pressure is controlled by one or a set of butterfly valves in the exhaust system. With this programmable valve control unit the opening and closing points of
