996 3.4/3.6 Catalytic Bypass X-Design for PSE exhaust

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_x000B__x000B_This item may need to be sourced from Germany and would take 2-4 weeks to arrive.
