Description
*With Sport Cats*
Fabspeed Motorsport introduces our cutting-edge modular headers, designed exclusively for the Porsche 981 Cayman GT4 and Boxster Spyder (2015-2016). These US patented RENNKRAFT™ modular headers feature an innovative quick-release V-band connector, allowing effortless transitions between HJS 200-cell catalytic converters and cat bypass pipes for track use. The term "Rennkraft," meaning "race power" in German, underscores the exceptional performance and engineering behind these headers.
SOUND: With our HJS German HD tri-metallic 200-cell sportcats, these headers produce a louder, more raw exhaust note. Higher frequency tones become more pronounced, and off-throttle burbles are both robust and transparent. When fitted with the cat bypass pipes (for track use only), the sound rivals that of a 911 CUP car, offering a very aggressive and race-bred character that dramatically enhances the driving experience.
