997 Sport Catalytics 100 cell (U-Design) 05-08

100 cell, HJS tri-metal, HF (High Flow) HJS catalytic cores with "U-Torque" design, manufactured by M&M in Germany. The U-Torque design compensates for the backpressure loss while running the high flow 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 more torque in the mid-range and minimize the loss of torque down low where the 997's need it most!! These catalytic converters do not require software and are safe for emissions testing. Tech Tip:Add one of our Installation kits FVD MK 997300
