The R1 high flow sports catalyzers for the Z34 Nissan 370Z and HR motor-equipped Z33 Nissan 350Z vehicles completes the full exhaust system. The high efficiency catalyst improves torque between the 3000 rpm and 5000rpm range throughout the midrange of the powerband. In combination with the R1 Titan Progress system for 370Z, the sound output is roughly 96db.
