997 Catalytic Bypass (u-design) for Porsche 911
997 CATALYTIC BYPASS (U-DESIGN)
R21011124 - Replacement/Accessory
Price: $687.94
Description
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 !
Fits: Carrera 4s, 3.8l, 261kw (05-08), Carrera 4, 3.6l, 239kw (05-08), Carrera s, Carrera
