These modular REKRAFT™ headers are the perfect solution for any street driven 4.0 liter Cayman or Boxster. Our patented modular design features a quick release V-band connector that allows the owner to easily swap between our German made HJS 200 cell cats and a cat bypass “straight pipes” for track use (patent pending). Rennkraft, translated from German is “race power”. These unique headers offer true street and racetrack functionality in an innovative precision engineered package.
