The GMG WC-Rennsport Exhaust and Header System for the Porsche 992 GT3 and GT3 RS is engineered with a singular focus: maximum flow, precision power delivery, and uncompromised sound.
Featuring long-tube stepped headers, the system optimizes exhaust gas velocity and scavenging across the entire RPM range, improving throttle response and sustaining top-end power. 3D-printed elbows and a motorsport-derived center X-merge enable seamless internal transitions and tighter mergers, reducing turbulence while balancing exhaust pulses for smoother, more efficient performance.
Finished with GT3R Rennsport-inspired exhaust tips, the WC-Rennsport system delivers a race-bred aesthetic and an unmistakably mechanical flat-six tone—refined, aggressive, and true to Porsche motorsport heritage.

Race-bred engineering. Precision performance. Pure Rennsport.
