These modular headers are the perfect solution for any Cayman or Boxster. Our patented RENNKRAFT™ 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.

SOUND:

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 off throttle 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.

FEATURES:

  • Fits all Porsche 981 Cayman GT4 / Boxster Spyder vehicles (2015-2016)
  • Constructed from CNC mandrel-bent T304L stainless steel
  • Impressive power and performance gains
  • Save 2 lbs / 0.9 KGs with Sport Cats and 7 lbs / 3.2 KGs with Cat Bypass compared to the factory headers
  • Modular design that uses a V-band clamp so one can quickly swap between cats and cat bypass
  • With the RENNKRAFT™ system, you can quickly install our QUICKTRACK™ cat bypass pipes for Racing and all out Race track-only competition events
  • The RENNKRAFT™ system has been awarded a US Patent and is the only system of its kind in the world
  • Switching to cat-bypass for track events prevents catalytic converter degradation during all out competition racing abuse
  • F1 style high velocity merge collectors
  • Designed from 3D scans of the OEM headers so we can achieve perfect bolt-on fitment
  • We use German-made HJS HD tri-metallic 200-cell EURO 6 homologated catalytic converters for the best performance and reliability
  • We use the largest catalytic converters that will fit in the factory location for maximum flow
  • Flows 93% of a 2.5 in straight pipe
  • Optimized for maximum performance with NO catalyst generated check engine light, guaranteed, when Sport Cats are installed
  • No ECU tune required
  • Will fit with any brand of aftermarket exhaust system designed to work with the factory headers

Decrease in black heads. Smoother skin!
Size: 1.01 Fl Oz (Pack of 1), Size: 1.01 Fl Oz (Pack of 1)
I’ve never used such a great pore minimizer for this reasonable of a price. I love how smooth and clean it makes my face feel. I’ve been using it twice a day after cleansing my skin. Noticeable difference in visible pores and decrease in black heads on my nose and chin. Highly recommend!! Come on with this price, you have nothing to lose.

Serum does not work to reduce pore size
Size: 1.01 Fl Oz (Pack of 1)
While this serum does somewhat smooth skin it does absolutely nothing to reduce pore size which is primarily genetic and is resistant to most products. Not worth the money.
