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

  • 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

Fun, interactive toy!
So much fun! Bought this for my lab. She wasn't sure what to think of it at first but seems to love it now! I like that it's rechargeable too.

Overall, I highly recommend it!”
Great toy! My dog loves it 🐶 The ball moves on its own and keeps him entertained for a long time. It’s perfect when I’m busy or not at home. Good quality and fun, but maybe not the best for very aggressive chewers.

Puppy loves it but the battery is awful
Color: Blue
Our puppy loves playing with this ball, it does what it says and keeps her occupied for the entire 10-15 minutes the battery lasts. I have to charge it several times a day, though the light never flashes red when the battery is low, it just doesn't work anymore. It also makes a beeping sound when she's playing with it that is super annoying, which sucks because the ball itself isn't super noisy even in the hardwood floors. I wouldn't purchase this again, and we'll probably have to toss it out within a week or two, I really don't see this thing lasting very long. Without the movement, it isn't a ball we would let her play with because she is a strong chewer and the material doesn't seem chew proof at all. I'm only giving it 2 stars because she really does love playing with it, but the battery life and beeping sound are atrocious.
