Make a selection 21011124OK Catalytic bypass pipe "u-torque" design, manufactured by m&m in Germany. The u-torque design compensates for the backpressure loss while running without cats. The design minimizes the loss of low end torque and adds 10-15 ft-lbs of torque in the mid and top range of the rpms. Why settle for the traditional cross over cat design when you can add torque in the mid-range and minimize the loss of torque down low where the 997's need it most! Ecu software is necessary !
