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 !

200 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.

Please note: not for cars with the Porsche® sport exhaust with valves.
