Make a selection 21011123PSE Catalytic bypass pipe "x torque" design made by m&m exhaust gmbh in Germany. The x torque design in is a true x pipe design. It is open in the center to add backpressure for torque. 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! Dme programming is necessary. Without it you will get a check engine light (cel). Please note: this is only for models with the optional valved Porsche sport exhaust (pse). We recommend replacing all of the hardware when installing, please use part # FVDmk996300 General Fitment911 1998-05

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 !

Make a selection 21011125PSE Only for vehicles with Porsche standard sports exhaust system 200 cell, hjs tri-metal, hf (high flow) hjs catalytic cores with "u-torque" design, manufactured by 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! Please note: these fit the OEM mufflers and Porsche sport exhaust (pse) mufflers. Tech tip:add one of our installation kits FVD mk 997300
