Descriptions:

These modular headers are the perfect solution for any street driven 4.0 liter Cayman or Boxster. Our 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. Rennkraft, translated from German is “race power”. These unique headers offer true street and racetrack functionality in an innovative precision engineered package.

Why We Choose HJS Catalytic Converters:

HJS German imported catalytic converters are made from some of the highest grade materials you can find in a catalytic converter. This yields high performance gains and longevity so it wont deteriorate over time like lower grade catalytic converters. These catalytic converters flow up to 93-95% of a straight pipe in most applications. The benefit is that you get the "straight pipe sound" while still being able to provide enough emissions scrubbing to prevent a check engine light. If you'd like to learn more, watch our video about HJS catalytic converters.

Sound:

Many have complained about the lack of sound with the new 718 4.0 Liter cars, these high flowing headers completely solve that issue. Equipped with our 200 cell cats, you will get a louder exhaust note with a much more raw sound. Higher frequency tones are more defined, and deceleration burbles are more robust and transparent. With the cat bypass pipes installed, you’re in store for a sound much more akin to a 911 CUP car than a Porsche street car. The volume isn’t overbearing, but the sound is very aggressive and race bred. It totally changes the character of the car. With the stock muffler in place, there is no drone what-so-ever, even with our Over Axle GPF Delete Pipes also installed.

Power:

These headers will add more power than any other single bolt on part. Significant gains can be seen throughout the entire RPM band. On our DynoJet we saw +24 whp and 26 ft/lbs of tq at 7,700 RPM and strong torque gains down low with gains of +26 ft/lbs of tq at 2,600 RPM and 21 ft/lbs of tq at 4,600 RPM. This is power that you will feel in the seat of your pants all the way to redline.
