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

  • F1 style high velocity merge collectors

  • 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

  • Will fit with any brand of aftermarket exhaust system designed to work with the factory headers

Stopped working the 2nd day
I realize I am the minority. This ball has great reviews. So it has to just be my bad luck. But it worked great the 1st day. Had some problems with getting it to turn on the next day. After that it never came on again. I bought new batteries and put 2 new batteries in it. It still did not light up. Other than that, it’s great and seems durable. I just can’t get the lights to work on it.

Very durable and my dog loves it.
This is a great ball for the dog. It is very durable and has led light inside. Easy for me to throw and great for playing with my dog. No noise just the lights. What a great value. Even the smaller dogs can play with this one. Smaller and lighter .

Sturdy For Chewers; Weeks Later Still Lights Up
This item is fantastic. We have two rottweilers and these two tou balls have stood the test of time. Weeks later and it STILL lights up! No other ball has survived our dogs. I highly recommend this item to anyone. Our dogs love the lights.
