200 cell German hjs sport catalysts with x torque design made by m&m in Germany. These catalytic converters are specially made for the valved Porsche sport exhaust.

The x torque design in is a true x pipe design. It is open in the center to add backpressure for torque. In combination with the free flowing 200 cell cats the x torque design give 's you 10-15 ft-lbs of torque in the mid range along with 10-15 hp in the higher rpms. Why settle for the traditional cross over cat design when you can add torque in the mid range where the 996 's need it most!
